********** REPORT OF PROTEIN ANALYSIS  by the WHAT IF program **********
************************************************************************

Date : 2025-03-22
This report was created by WHAT IF version WHATCHECK15.0

This document is a WHAT_CHECK 14.0 report for a PDB-file. Each reported
fact has an assigned severity, one of:

error  : Items marked as errors are considered severe problems requiring
         immediate attention.
warning: Either less severe problems or uncommon structural features. These
         still need special attention.
note   : Statistical values, plots, or other verbose results of tests and
         analyses that have been performed.

If alternate conformations are present, only the first is evaluated. Hydrogen
atoms are only included if explicitly requested, and even then they are not
used in all checks. The software functions less well for non-canonical amino
acids and exotic ligands than for the 20 canonical residues and canonical
nucleic acids.

Some remarks regarding the output:

Residues/atoms in tables are normally given in a few parts:

A number. This is the internal sequence number of the residue used by WHAT IF.
    The first residues in the file get number 1, 2, etc.
The residue type. Normally this is a three letter amino acid type.
The sequence number, between brackets. This is the residue number as it was
    given in the input file. It can be followed by the insertion code.
The chain identifier. A single character. If no chain identifier was given in
    the input file, this will be a minus sign or a blank.
A model number. If no model number exists, like in most X-ray files, this will
    be a blank or occasionally a minus sign.
In case an atom is part of the output, the atom will be listed using the PDB
    nomenclature for type and identifier.

To indicate the normality of a score, the score may be expressed as a Z-value
   or Z-score. This is just the number of standard deviations that the score
   deviates from the expected value. A property of Z-values is that the
   root-mean-square of a group of Z-values (the RMS Z-value) is expected to be
   1.0. Z-values above 4.0 and below -4.0 are very uncommon. If a Z-score is
   used in WHAT IF, the accompanying text will explain how the expected value
   and standard deviation were obtained.
The names of nucleic acids are DGUA, DTHY, OCYT, OADE, etc. The first character
   is a D or O for DNA or RNA respectively. This circumvents ambiguities in the
   many old PDB files in which DNA and RNA were both called A, C, G, and T.

# 1 # Note: Introduction
WHAT CHECK needs to read a PDB file before it can check it. It does a
series of checks upon reading the file. The results of these checks are
reported in this section (section 2.1). The rest of the report will be more
systematic in that section 2.2 reports on administrative problems. Section
2.3 gives descriptive output that is not directly validating things but
more telling you how WHAT CHECK interpreted the input file. Section 2.4
looks at B-factors, occupancies, and the presence/absence of (spurious)
atoms. Section 2.5 deals with nomenclature problems. Section 2.6 deals with
geometric problems like bond lengths and bond angles. Section 2.7 deals with
torsion angle issues. Section 2.8 looks at atomic clashes. Section 2.9 deals
with packing, accessibility, etc, issues. Section 2.10 deals with hydrogen
bonds, ion packing, and other things that can be summarized under the common
name charge-charge interactions. Section 2.11 gives a summary of whole report
and tells you (if applicable) which symmetry matrices were used. Section 2.12
tells the crystallographer which are the things most in need of manual
correction. And the last section, section 2.13, lists all residues sorted
by their need for visual inspection in light of the electron density.

# 5 # Warning: Problem detected upon counting molecules and matrices
The parameter Z as given on the CRYST card represents the molecular
multiplicity in the crystallographic cell. Normally, Z equals the number of
matrices of the space group multiplied by the number of NCS relations. The
value of Z is multiplied by the integrated molecular weight of the molecules
in the file to determine the Matthews coefficient. This relation is being
validated in this option. Be aware that the validation can get confused if
both multiple copies of the molecule are present in the ATOM records and
MTRIX records are present in the header of the PDB file.

# 6 # Error: Matthews Coefficient (Vm) very high
 
The Matthews coefficient [REF] is defined as the density of the protein
structure in cubic Angstroms per Dalton. Normal values are between 1.5
(tightly packed, little room for solvent) and 4.0 (loosely packed, much
space for solvent). Some very loosely packed structures can get values a bit
higher than that.
 
Numbers this high are almost always caused by giving the wrong value for Z
on the CRYST1 card (or not giving this number at all).
 
 Molecular weight of all polymer chains: 33844.113
 Volume of the Unit Cell V= 455004.531

# 9 # Warning: Ligands for which a topology was generated automatically
The topology for the ligands in the table below were determined
automatically. WHAT CHECK uses a local copy of the CCP4 monomer library to
generate topology information for ligands. Be aware that automatic topology
generation is a complicated task. So, if you get messages that you fail to
understand or that you believe are wrong, and one of these ligands is
involved, then check the ligand topology entry first. This topology is either
present in the monomer library, or as a libcheck-generated file in the local
directory.

# 21 # Note: Ramachandran plot
In this Ramachandran plot x-signs represent glycines, squares represent
prolines, and plus-signs represent the other residues. If too many
plus-signs fall outside the contoured areas then the molecule is poorly
refined (or worse). Proline can only occur in the narrow region around
phi=-60 that also falls within the other contour islands.
 
In a colour picture, the residues that are part of a helix are shown in blue,
strand residues in red. Preferred regions for helical residues are drawn in
blue, for strand residues in red, and for all other residues in green. A full
explanation of the Ramachandran plot together with a series of examples can
be found at the WHAT CHECK website [REF].

# 22 # Note: Secondary structure
This is the secondary structure according to DSSP. Only helix (H), overwound

All DSSP related information can be found at swift.cmbi.ru.nl/gv/dssp/
This is not really a structure validation option, but a very scattered
secondary structure (i.e. many strands of only a few residues length, many
Ts inside helices, etc) tends to indicate a poor structure. A full
explanation of the DSSP secondary structure determination program together
with a series of examples can be found at the WHAT CHECK website [REF].

separately.
 
# 26 # Warning: B-factors outside the range 0.0 - 100.0
In principle, B-factors can have a very wide range of values, but in
practice, B-factors should not be zero while B-factors above 100.0
are a good indicator that the location of that atom is meaningless. Be
aware that the cutoff at 100.0 is arbitrary. 'High' indicates that atoms
with a B-factor > 100.0 were observed; 'Zero' indicates that atoms with
a B-factor of zero were observed.

# 27 # Note: C-terminus capping
The residues listed in the table below are either C-terminal or pseudo
C-terminal (i.e. last residue before a missing residue).
In X-ray the coordinates must be located in density. Mobility or disorder
sometimes cause this density to be so poor that the positions of the atoms
cannot be determined. Crystallographers tend to leave out the atoms in such
cases. In many cases the N- or C-terminal residues are too disordered to see.
In case of the N-terminus, you can often see from the residue numbers if
there are missing residues; at the C-terminus this is impossible. Therefore,
often the position of the backbone nitrogen of the first residue missing
at the C-terminal end is calculated and added to indicate that there
are missing residues. As a single N causes validation trouble, we remove
these single-N-residues before doing the validation. If this happened,
the label -N is added to the pseudo C-terminus. Other labels can be +X
in case something weird is bound to the backbone C, or +OXT if a spurious
OXT atom is found. -OXT indicates that an expected OXT is missing. 'Swap'
means that the O' and O'' (O and OXT in PDB files) have been swapped in
terms of nomenclature. 'Bad' means that something bad happened that WHAT IF
does not understand. In such cases you might get three residue numbers in
square brackets; one of those might be what WHAT IF had expected to find,
but then it also might not). In case of chain breaks the number of missing
residues is listen in round brackets. OK means what it suggests...
 
Be aware that we cannot easily see the difference between these errors and
errors in the chain and residue numbering schemes. So do not blindly trust
the table below. If you get weird errors at, or near, the left-over
incomplete C-terminal residue, please check by hand if a missing Oxt or
a removed single N is the cause. Also, many peptidic ligands get the same
chain identifier as the larger protein they are bound to. In such cases there
are more than one C-termini and OXTs with the same ID. WHAT IF gives some
random warnings about these cases. So, don't take everything at face value,
but think for yourself.

# 28 # Note: Weights administratively correct
All atomic occupancy factors ('weights') fall in the 0.0--1.0 range, which
makes them administratively correct.
 
# 29 # Note: Normal distribution of occupancy values
 
The distribution of the occupancy values in this file seems 'normal'.
 
Be aware that this evaluation is merely the result of comparing this file
with about 500 well-refined high-resolution files in the PDB. If this file
has much higher or much lower resolution than the PDB files used
in WHAT CHECK's training set, non-normal values might very well be perfectly
fine, or normal values might actually be not so normal. So, this check is
actually more an indicator and certainly not a check in which I have great
confidence.
 
# 30 # Note: All occupancies seem to add up to 0.0 - 1.0.
In principle, the occupancy of all alternates of one atom should add up till
0.0 - 1.0. 0.0 is used for the missing atom (i.e. an atom not seen in the
electron density). Obviously, there is nothing terribly wrong when a few
occupancies add up to a bit more than 1.0, because the mathematics of
refinement allow for that. However, if it happens often, it seems worth
evaluating this in light of the refinement protocol used.
 
# 31 # Warning: What type of B-factor?
WHAT CHECK does not yet know well how to cope with B-factors in case TLS has
been used. It simply assumes that the B-factor listed on the ATOM and HETATM
cards are the total B-factors. When TLS refinement is used that assumption
sometimes is not correct. The header of the PDB file states that TLS groups
were used. So, if WHAT CHECK complains about your  B-factors, while you think
that they are OK, then check for TLS related B-factor problems first.
 
Number of TLS groups mentione in PDB file header: 1
 
Temperature not mentioned in PDB file. This most likely means
that the temperature record is absent.
Room temperature assumed
 
# 32 # Note: Number of buried atoms with low B-factor is OK
For protein structures determined at room temperature, no more than about 1
percent of the B factors of buried atoms is below 5.0. In liquid
nitrogen this percentage is allowed to be higher, of course.
 
Percentage of buried atoms with B less than 5 :   0.00
 
# 33 # Warning: Analysis of bonded atoms indicate B-factor problems
For each of the bond types in a protein a distribution was derived for the
difference between the square roots of the B-factors of the two atoms. All
bonds in the current protein were scored against these distributions. The
number given below is the RMS Z-score over the structure. For a structure
with completely restrained B-factors, this value will be around 0.35, for
extremely high resolution structures refined with free isotropic B-factors
this number is expected to be near 1.0. A value over 1.5 is a sign of
under-contraining of the B-factors during refinement.
 
RMS Z-score :  2.089 over    2099 bonds
Average difference in B over a bond :    6.16
RMS difference in B over a bond :    8.91
 
# 34 # Note: B-factor plot
The average atomic B-factor per residue is plotted as function of the residue
number.

# 35 # Note: Introduction to the nomenclature section.
Nomenclature problems seem, at first, rather unimportant. After all who
cares if we call the delta atoms in leucine delta2 and delta1 rather than
the other way around. Chemically speaking that is correct. But structures
have not been solved and deposited just for chemists to look at them. Most
times a structure is used, it is by software in a bioinformatics lab. And
if they compare structures in which the one used C delta1 and delta2 and the
other uses C delta2 and delta1, then that comparison will fail. Also, we
recalculate all structures every so many years to make sure that everybody
always can get access to the best coordinates that can be obtained from
the (your?) experimental data. These recalculations will be troublesome if
there are nomenclature problems.
 
Several nomenclature problems actually are worse than that. At the
WHAT CHECK website [REF] you can get an overview of the importance of all
nomenclature problems that we list.

# 46 # Note: Heavy atom naming OK
No errors were detected in the atom names for non-hydrogen atoms. Please

# 47 # Note: No decreasing residue numbers
All residue numbers are strictly increasing within each chain.
 
# 48 # Note: All bond lengths OK
All bond lengths are in agreement with standard bond lengths using a
tolerance of 4 sigma (both standard values and sigma for amino acids
have been taken from Engh and Huber [REF], for DNA/RNA from Parkinson
et al [REF]).
 
# 49 # Warning: Low bond length variability
Bond lengths were found to deviate less than normal from the mean Engh and
Huber [REF] and/or Parkinson et al [REF] standard bond lengths. The RMS
Z-score given below is expected to be near 1.0 for a normally restrained
data set. The fact that it is lower than 0.667 in this structure might
indicate that too-strong restraints have been used in the refinement. This
can only be a problem  for high resolution X-ray structures.
 
 RMS Z-score for bond lengths: 0.610
 RMS-deviation in bond distances: 0.015
 
# 50 # Note: No bond length directionality
Comparison of bond distances with Engh and Huber [REF] standard values for
protein residues and Parkinson et al [REF] values for DNA/RNA does not show
significant systematic deviations.
 
# 51 # Warning: Unusual bond angles
The bond angles listed in the table below were found to deviate more than 4
sigma from standard bond angles (both standard values and sigma for protein
residues have been taken from Engh and Huber [REF], for DNA/RNA from
Parkinson et al [REF]). In the table below for each strange angle the bond
angle and the number of standard deviations it differs from the standard
values is given. Please note that disulphide bridges are neglected. Atoms
starting with "-" belong to the previous residue in the sequence.

# 52 # Note: Normal bond angle variability
Bond angles were found to deviate normally from the mean standard bond angles
(normal values for protein residues were taken from Engh and Huber [REF], for
DNA/RNA from Parkinson et al [REF]). The RMS Z-score given below is expected
to be near 1.0 for a normally restrained data set, and this is indeed
observed for very high resolution X-ray structures.

# 53 # Note: Residue hand check OK
No atoms are observed that have the wrong handedness. Be aware, though, that
WHAT CHECK might have corrected the handedness of some atoms already. The
handedness has not been corrected for any case where the problem is worse
than just an administrative discomfort.

All protein atoms have proper chirality, or there is no intact protein
present in the PDB file.
The average deviation= 1.107

The RMS Z-score for all improper dihedrals in the structure is within normal
ranges.
 
 Improper dihedral RMS Z-score : 0.950
 
# 56 # Note: Tau angles OK
All of the tau angles (N-C-alpha-C) of amino acids fall within expected
RMS deviations.
 
# 57 # Note: Normal tau angle deviations
The RMS Z-score for the tau angles (N-C-alpha-C) in the structure falls
within the normal range that we guess to be 0.5 - 1.5. Be aware, we
determined the tau normal distributions from 500 high-resolution X-ray
structures, rather than from CSD data, so we cannot be 100 percent certain
about these numbers.
 
 Tau angle RMS Z-score : 1.042
 
# 58 # Note: Side chain planarity OK
All of the side chains of residues that have an intact planar group are
planar within expected RMS deviations.
 
# 59 # Note: Atoms connected to aromatic rings OK
All of the atoms that are connected to planar aromatic rings in side chains
of amino-acid residues are in the plane within expected RMS deviations.
Since there is no DNA and no protein with hydrogens, no uncalibrated
planarity check was performed.
 
# 60 # Note: Ramachandran Z-score OK

correspond to the known allowed areas in the Ramachandran plot is within
expected ranges for well-refined structures.
 
 Ramachandran Z-score : -2.703
 
# 61 # Note: Ramachandran check
The list contains per-residue Z-scores describing how well each residue
fits into the allowed areas of the Ramachandran plot will not be printed
because WHAT CHECK found no reason to cry.
 
# 62 # Warning: Torsion angle evaluation shows unusual residues
The residues listed in the table below contain bad or abnormal
torsion angles.
 
These scores give an impression of how `normal' the torsion angles in
protein residues are. All torsion angles except omega are used for
calculating a `normality' score. Average values and standard deviations were
obtained from the residues in the WHAT CHECK database. These are used to
calculate Z-scores. A residue with a Z-score of below -2.0 is poor, and a
score of less than -3.0 is worrying. For such residues more than one torsion
angle is in a highly unlikely position.

# 66 # Warning: Unusual rotamers
The residues listed in the table below have a rotamer that is not seen very
often in the database of solved protein structures. This option determines
for every residue the position specific chi-1 rotamer distribution.
Thereafter it verified whether the actual residue in the molecule has the
most preferred rotamer or not. If the actual rotamer is the preferred one,
the score is 1.0. If the actual rotamer is unique, the score is 0.0. If
there are two preferred rotamers, with a population distribution of 3:2 and
your rotamer sits in the lesser populated rotamer, the score will be 0.667.
No value will be given if insufficient hits are found in the database.
 
It is not necessarily an error if a few residues have rotamer values below
0.3, but careful inspection of all residues with these low values could be
worth it.

For the residues listed in the table below, the backbone formed by itself and
two neighbouring residues on either side is in a conformation that is not

For this check, backbone conformations are compared with database structures
using C-alpha superpositions with some restraints on the backbone oxygen
positions.
 
A residue mentioned in the table can be part of a strange loop, or there
might be something wrong with it or its directly surrounding residues. There
are a few of these in every protein, but in any case it is worth looking at,
especially if a regular DSSP secondary structure (H or S for helix or strand,
respectively) is indicated!

The omega angles for trans-peptide bonds in a structure is expected to give
a gaussian distribution with the average around +178 degrees, and a standard

this distribution is above 7.0, which indicates that the omega values have

# 72 # Warning: Backbone oxygen evaluation
The residues listed in the table below have an unusual backbone oxygen
position.
 
For each of the residues in the structure, a search was performed to find
5-residue stretches in the WHAT CHECK database with superposable C-alpha
coordinates, and some restraints on the neighbouring backbone oxygens.
 
In the following table the RMS distance between the backbone oxygen positions
of these matching structures in the database and the position of the backbone
oxygen atom in the current residue is given. If this number is larger than
1.5 a significant number of structures in the database show an alternative
position for the backbone oxygen. If the number is larger than 2.0 most
matching backbone fragments in the database have the peptide plane flipped.
A manual check needs to be performed to assess whether the experimental data
can support that alternative as well. The number in the last column is the
number of database hits (maximum 80) used in the calculation. It is "normal"
that some glycine residues show up in this list, but they are still worth
checking!

For the residues listed in the table below, the backbone formed by the
residue mentioned and the one N-terminal of it show systematic deviations
from normality that are consistent with a peptide flip. This can either
be a 180 degree flip of the entire peptide plane or a trans to cis flip.
(Cis to trans flips cannot be detected yet). The type can be TT+, TC-,
or TC+:
TT+ indicates a 180 degree flip of the entire peptide plane.
TC- indicates a trans to cis conversion that requires a flip of the N atom.
TC+ indicates a trans to cis conversion that requires a flip of the O atom.
Note that the method will only work correctly for PDB files with full
isotropic B-factors.

# 74 # Error: Abnormally short interatomic distances
The pairs of atoms listed in the table below have an unusually short
interactomic distance; each bump is listed in only one direction.
 
The contact distances of all atom pairs have been checked. Two atoms are
said to `bump' if they are closer than the sum of their Van der Waals radii
minus 0.40 Angstrom. For hydrogen bonded pairs a tolerance of 0.55 Angstrom
is used. The first number in the table tells you how much shorter that
specific contact is than the acceptable limit. The second distance is the
distance between the centres of the two atoms. Although we believe that two
water atoms at 2.4 A distance are too close, we only report water pairs that
are closer than this rather short distance.
 
INTRA and INTER indicate whether the clashes are between atoms in the same
asymmetric unit, or atoms in symmetry related asymmetric units, respectively.
The last text-item on each line represents the status of the atom pair. If
the final column contains the text 'HB', the bump criterion was relaxed
because there could be a hydrogen bond. Similarly relaxed criteria are used
for 1--3 and 1--4 interactions (listed as 'B2' and 'B3', respectively).
If the last column is 'BF', the sum of the B-factors of the atoms is higher
than 80, which makes the appearance of the bump somewhat less severe because
the atoms probably are not there anyway. BL, on the other hand, indicates
that the bumping atoms both have a low B-factor, and that makes the bumps
more worrisome.
 
Bumps between atoms for which the sum of their occupancies is lower than one
are not reported. If the MODEL number does not exist (as is the case in most
X-ray files), a minus sign is printed instead.

of the sequence through the density, crystal contacts, contacts with a
co-factor, or the residue is part of the active site. It is not uncommon to
see a few of these, but in any case this requires further inspection of the

# 86 # Warning: No crystallisation information
No, or very inadequate, crystallisation information was observed upon
reading the PDB file header records. This information should be available
in the form of a series of REMARK 280 lines. Without this information a
few things, such as checking ions in the structure, cannot be performed
optimally.
 
# 87 # Note: Water contacts OK
All water clusters make at least one contact with a non-water atom.
 
# 88 # Note: No waters need moving
All water molecules are sufficiently close to the asymmetric unit given in
the input file.
 
# 89 # Note: Water hydrogen bonds OK
All water molecules can form hydrogen bonds.
 
# 90 # Note: His, Asn, Gln side chains OK
All of the side chain conformations of Histidine, Asparagine and Glutamine
residues were found to be optimal for hydrogen bonding.
 
# 91 # Note: Histidine type assignments
For all complete HIS residues in the structure a tentative assignment to
HIS-D (protonated on ND1), HIS-E (protonated on NE2), or HIS-H (protonated
on both ND1 and NE2, positively charged) is made based on the hydrogen bond
network. A second assignment is made based on which of the Engh and Huber
[REF] histidine geometries fits best to the structure.
 
In the table below all normal histidine residues are listed. The assignment
based on the geometry of the residue is listed first, together with the RMS
Z-score for the fit to the Engh and Huber parameters. For all residues where
the H-bond assignment is different, the assignment is listed in the last
columns, together with its RMS Z-score to the Engh and Huber parameters.
 
As always, the RMS Z-scores should be close to 1.0 if the residues were
restrained to the Engh and Huber parameters during refinement, and if
enough (high resolution) data is available.
 
Please note that because the differences between the geometries of the
different types are small it is possible that the geometric assignment given
here does not correspond to the type used in refinement. This is especially
true if the RMS Z-scores are much higher than 1.0.
 
If the two assignments differ, or the `geometry' RMS Z-score is high, it is
advisable to verify the hydrogen bond assignment, check the HIS type used
during the refinement and possibly adjust it.

# 92 # Warning: Buried unsatisfied hydrogen bond donors
The buried hydrogen bond donors listed in the table below have a hydrogen
atom that is not involved in a hydrogen bond in the optimized hydrogen bond
network.
 
Hydrogen bond donors that are buried inside the protein normally use all of
their hydrogens to form hydrogen bonds within the protein. If there are any
non hydrogen bonded buried hydrogen bond donors in the structure they will
be listed here. In very good structures the number of listed atoms will tend
to zero.
 
Waters are not listed by this option.

# 93 # Note: Buried hydrogen bond acceptors OK
All buried polar side-chain hydrogen bond acceptors are involved in a
hydrogen bond in the optimized hydrogen bond network.
 
# 94 # Note: Some notes regarding these donors and acceptors
The donors and acceptors have been counted, also as function of their
accessibility. The buried donors and acceptors have been binned in five
categories ranging from not forming any hydrogen bond till forming a poor
till perfect hydrogen bond. Obviously, the buried donors and acceptors
with no or just a poor hydrogen bond should be a topic of concern. As every
protein contains more acceptors than donors, unsatisfied donors are more in
need of attention than unsatisfied acceptors.

# 96 # Note: Summary report
This is an overall summary of the quality of the structure as compared with
current reliable structures. Numbers in brackets are the average and standard
deviation observed for a large number of files determined with a similar
resolution.
 
The second table mostly gives an impression of how well the model conforms
to common refinement restraint values. These numbers are less than 1.0 if the
spread in data is too little, and larger than 1.0 when the spread is too
large. The former does not need to be a problem, the latter always is bad.
 
 Structure Z-scores, positive is better than average:
  Resolution read from PDB file  :   1.930
  1st generation packing quality :  -0.193 (          (  -0.3,  2.5))
  2nd generation packing quality :  -0.784 (          (  -1.1,  1.4))
  Ramachandran plot appearance   :  -2.703 (          (  -0.9,  1.2))
  chi-1/chi-2 rotamer normality  :  -2.539 (          (  -2.5,  1.4))
  Backbone conformation          :  -0.278 (          (  -0.5,  3.3))
  Inside/Outside distribution    :   0.984
 
 RMS Z-scores, should be close to 1.0:
  Bond lengths                   :   0.610 (tight)
  Bond angles                    :   0.870

# 97 # Note: Introduction to refinement recommendations
First, be aware that the recommendations for crystallographers listed below
are produced by a computer program that was written by a guy who got his
PhD in NMR...
 
We have tried to convert the messages written in this report into a small
set of things you can do with your refinement software to get a better
structure. The things you should do first are listed first. And in some
cases you should first fix that problem, then refine a bit further, and
then run WHAT CHECK again before looking at other problems. If, for example,
WHAT CHECK has found a problem with the SCALE and CRYST cards, then you must
first fix that problem, refine the structure a bit further, and run WHAT
CHECK again because errors in the SCALE and or CRYST card can lead to many
problems elsewhere in the validation process.
 
It is also important to keep in mind that WHAT CHECK is software and that it
occasionally totally misunderstands what is the cause of a problem. But, if
WHAT CHECK lists a problem there normally is a problem albeit that it not
always is the actual problem that gets listed.
 
# 98 # Note: Matthews coefficient problem
WHAT CHECK detected a Matthews coefficient problem. Most times this is an
administrative problem caused by typing the wrong cell multiplicity number
on the CRYST card (or not typing it at all). Occasionally it is caused by
typing the wrong space group on the CRYST card. You better fix this problem,
but normally this problem does not cause WHAT CHECK to give any erroneous
error messages further down in the report.
 
# 99 # Error: Bumps in your structure
Upon analysing the bumps in your structure, WHAT CHECK got a bit
worried. Sometimes this means that you have forgotten to lower the
occupancy of overlapping ligands, residues, or water molecules. But,
whatever is the origin of this problem, you have to analyse it and
fix it.
 
# 100 # Note: Omega angles insufficiently restraint
Omega angles tend to fall around 178 degrees with a standard deviation of 5.5
degrees. Even with a resolution of 1.5-2.5 Angstrom, you dont have enough
data to warrant the omega angle variability that we observed. The variability
is larger than 7.0 degrees. So, especially if your resolution is closer to
2.5 than to 1.5 Angstrom, you might want to tighten the screws on the
omega angle target values a bit.
 
# 101 # Warning: Troublesome residues
The residues listed in the table below need to be inspected
 
This table is a very rough attempt to sort the residues according to how
badly they need your attention. The idea is that when you sit in  in front
of the graphics screen and study the residues with the electron density
present that you improve the structure most by dealing with the top residues
in this list first.
