For human groups:
AUTHOR XXXX-XXXX-XXXX
XXXX-XXXX-XXXX indicates the Group Leader's registration code.
This code is the prediction submission code obtained upon
CASP7 group registration.
Members of prediction groups who intend to submit predictions
should use the registration code of the Group Leader for all
predictions submitted by that group.
For server groups:
AUTHOR MY_GROUP_NAME
where MY_GROUP_NAME is a name selected for the group at registration.
Alternative way of identification for server groups:
REMARK AUTHOR MY_GROUP_NAME
SCORE Optional. This record may be used to report a model
reliability score. It will not influence the evaluation.
REMARK Optional. PDB style 'REMARK' records may be used
anywhere in the submission. These records may contain any
text and will in general not influence evaluation.
Records METHOD are used for all submissions.
These records describe the methods used. Predictors are urged to provide
as full a description of the methods as possible, including references,
data libraries used, and values of default and non-default parameters.
These descriptions will be made available via the Prediction Center WEB
pages as well as printed along with the other materials distributed at the
meeting. Length of 100 - 500 words is suggested.
Record MODEL is used for all submissions.
Signifies the beginning of model data (3D atomic coordinates, an unambiguous
alignment to a PDB entry, residue-residue separation distance prediction and
order-disorder region predictions).
MODEL n [REFINED|UNREFINED]
n Model index n is used to indicate predictor's ranking
according to her/his belief which model is closest to the
target structure (1 <= n <= 5). Model index is included
automatically in the ACCESSION CODE. All models with index
higher than 5 will be discarded.
REFINED The set of coordinates labeled REFINED will be considered
as a final model (to allow the evaluation of the results
of an automated refinement process, such as molecular
dynamics). Models submitted without any label: REFINED or
UNREFINED will be considered by default as final.
UNREFINED Coordinates labeled UNREFINED will be compared only to
the final set (REFINED) with the same model index n, to
evaluate the effectiveness of the refinement method. If
UNREFINED model is submitted, a REFINED model must be
submitted as well. The letter "u" will be added to the
model index in the ACCESSION CODE of the UNREFINED model.
Record PARENT is used for all submissions in the TS (and AL)
format.
PARENT record indicates structure templates used to generate any independent
segment of MODEL (see description of the TS format below).
The PARENT record should be placed as the first record of any such independent
segment. Only one PARENT record per structure segment is allowed.
PARENT N/A
Indicates an ab initio prediction, not directly based on any known
structure. Note that this is the only indication in the file that the
prediction is ab initio, so is a critical piece of information.
PARENT NONE [n1 n2]
Indicates that the predictor believes that there is no structure in
the present PDB that is close enough to be used as a template. This
is an entry requested by those predictors who use threading and
sequence comparison methods. With structural genomics projects being
designed to determine the structure of proteins with novel folds, the
ability to predict when a fold is unknown is becoming increasingly
important, and predictors are urged to make such submissions.
Delimiters n1 n2 indicate the range of the target sequence predicted
as having no homologue in the current PDB.
Omission of n1 n2 indicates the entire target (see Example 1 (C)).
PARENT mabc_A
Indicates that the model or the independent segment of structure is
based on a single PDB entry mabc chain A (use _A to indicate chain A).
Most threading and sequence search submissions would now be submitted
with this form of the PARENT record. A comparative modeler using a
single parent structure would also use this form. Note that, in order
to be accepted, the code must correspond to a current PDB entry.
PARENT mcdc ndef_g [ohij_k ...]
Is used only in comparative modeling and indicates that the model is
based on more than one structure template. Up to five PDB chains
may be listed here with additional detailed information included in
the METHOD records. In threading and sequence search, subdomains of
the target structure found to correspond to different known folds
should be submitted as independent segments of structure with
reference to only one PDB chain per segment.
Record TER is used to terminate an independent segment of structure
(PFRMAT TS and PFRMAT AL).
TER
3D atomic coordinates (PFRMAT TS).
Standard PDB atom records are used for the atomic coordinates. Format of the
submission requires that 80 column long records are used. These may be spaces
when needed (see target template PDB files as provided in specific target
descriptions available through the
CASP7 target table). This requirement is
necessitated by some of the software used in the evaluation of predictions.
Coordinates for each model or an independent structure segment should begin with a single PARENT record and terminate with a TER record (see above).
It is requested that coordinate data be supplied for at least all non-hydrogen main chain atoms, i.e. the N, CA, C and O atoms of every residue. Specifically, if only CA atoms are predicted by the method, predictors are encouraged to build the main chain atoms for every residue before submission to CASP. One program that can make such a conversion is Maxsprout server of Liisa Holm and co-workers. (If only CA atoms were submitted it would not be possible to run most of the analysis software, which would severely limit the evaluation of that prediction.) When multiple independent segments of structure are used in a prediction, they will be evaluated separately with no assumption of a common frame of reference between the segments. For any given MODEL, no target residue may be repeated among all such independent structure segments. Potential multi-domain nature of targets will be addressed in the evaluation even if the prediction is made in a single frame of reference (i.e. without separation into multiple segments of structure). For such predictions segmentation should only be used to allow multiple model predictions (effectively up to 5 predictions for each such domain).
Notes:
- atoms for which a prediction has been made must contain "1.0" in
the occupancy field; those for which no prediction is made must
either contain "0.0" in that field or be skipped altogether
- error estimates, in Angstroms, when given should be provided in the
temperature factor field
An unambiguous alignment to a PDB entry used for threading predictions
(PFRMAT AL).
Alignment for each model or an independent structure segment should begin
with a single PARENT record and terminate with a TER record (see above).
The (four column) alignment data records provide: target residue one
letter symbol, target residue sequence number, PDB residue one letter symbol,
and PDB residue sequence number with an insertion code if necessary
(see Example 3):
aa1 n1 aa2 n2
Note:
- residues for which no prediction is made must be skipped
- if a chain ID is specified in the PDB template of the target, then
the target residue sequence number should be composed of a chain ID
and residue number, e.g. A2, B44
The PDB code with chain extension of the structure the alignment is based on
should be placed in the PARENT record.
Only one PDB code per independent structure segment is allowed.
PDB codes should refer to structures containing at least the main chain atomic
coordinates (see the TS format).
As in the case of coordinate submissions,
when multiple independent segments of structure are used in a prediction,
they will be evaluated separately with no assumption of a common
frame of reference between the segments. For any given MODEL, no target
residue may be repeated among all such independent structure
segments. Potential multi-domain
nature of targets will be addressed in the evaluation even if the prediction
is made in a single frame of reference (i.e. without separation into multiple
segments of structure). For such predictions segmentation should only be
used to allow multiple model predictions (effectively up to 5 predictions
for each such domain).
Note:
The facility to translate sequence - structure alignments (AL format) into
standard PDB atom records (TS format) is available as an additional
AL2TS service.
Residue-Residue separation prediction (PFRMAT RR).
Data in this format are inserted between MODEL and END records of the
submission file.
Format for the predicted separation distance between pairs of residues.
The distance is defined as the separation between C-beta atoms (C-alpha for
glycine residues).
The (five column) RR format:
i j d1 d2 p
Notes (see Example 2):
- entire target sequence should be split over multiple lines with a
maximum of 50 residues per line
- for intrachain residue-residue contacts residue number indices
i and j should be used for distance specification (i < j), i.e.
only one diagonal of the separation matrix should be supplied
- the distances d1 and d2 (real numbers) should indicate the range of
Cb-Cb distance predicted for the residue pair (C-alpha for glycines)
- the real number p should range from 0.0 - 1.0 to indicate
probability of the distance falling between the predicted range
- residue 'contacts' (defined here - as in CASP2 - as Cb-Cb<8A) can be
predicted with this format as:
i j 0 8 p
- any pair NOT listed is assumed to be NOT considered by predictor
Order-disorder regions prediction (PFRMAT DR).
Data in this format are inserted between MODEL and END
records of the submission file.
The (three column) format record consists of residue code, Order/Disorder
prediction code, and a number specifying the associated confidence level:
aa OD pThe symbols for the 2 state order/disorder prediction are 'O'=order, 'D'=disorder. Last column should indicate a probability of a residue being in the disordered region. The value of this confidence level is in the range of 0.0 - 1.0. The entire sequence of the target should always be given. If parts cannot be predicted a probability of 0.5 should be used (see Example 5).
Domain boundary prediction (PFRMAT DP).
Data in this format are inserted between MODEL and END
records of the submission file.
You may also specify PARENT field (optional) if you used homologues
in assigning domains. It should be only one parent field per model and
order of parents should correspond to the domain number, i.e. parent listed
first corresponds to the domain assigned by you as number 1 and so on.
The format record consists of consecutive residue number n ,
residue code aa, domain number D and reliability score p
(a real number between 0 (unreliable) and 1 (sure), optional).
n aa D pThe domain numbers are Arabic numerals going from 1 (for the first domain) to N for the N-th domain (which allows split domains to be easily coded). Put a dash '-' instead of a domain number if you cannot predict the domain for a particular residue. (see Example 6).
Protein function prediction (PFRMAT FN).
Data are inserted between MODEL and END records of the submission file
(see Example 7 at the bottom of the page).
The data consist of four lines, each line starting with one of the
following keywords
GO Molecular Function:
EC number:
Binding site:
Prediction techniques:
and any additional number of lines starting with the keyword
Comment:
The format for each of the lines is described below (angle brackets designate optional/additional data and should not be included into the prediction; semicolon separates several entries on one row, e.g. different GO functions or different binding sites, etc. ; comma separates entries within the same logical block, e.g. numbers of residues within the same binding site or numbers of residues related to GO category):
GO Molecular Function: N1 <, res1 - res2 ; N2 , res3-res4 ; ...>
** Ni is a Genome Ontology identifier; resi (i=1, 2, ...) is a residue number in the target
EC number: N1.N2.N3.N4 <, res1-res2 ; M1.M2.M3.M4 , res3-res4 ; ...>
where Ni (Mi), i=1-4, are integer numbers from the
Enzyme Nomenclature Table
** Non enzymes should be labeled as 0.0.0.0
Binding site: res1, res2, ...
or
Binding site: res1 - res2, <res3 - res4>, ...
** Residues considered as binding sites are those in direct contact with
heteroatoms bound in the structure of the target protein. For the purposes of binding site residues predictors should be aiming to predict residues that have any atom in contact with the ligand at a distance of 0.5A plus the van der Waals radii.
For example under this defintion the vast majority of single magnesium atoms are in contact with 2-4 residues per chain and ATP is usually bound by 11-18 residues per chain.
Over-prediction of binding residues will not be advantageous.
Prediction techniques: N1.N2.N3.N4.N5.N6
where Ni (i=1-6) is either 0 (for "not used") or 1 (for "used") in a vector
of six numbers (e.g. 1.1.0.0.1.0) corresponding to:
N1 Sequence analysis
N2 Feature based predictions (e.g. sequence composition, postranslational
modifications, etc.)
N3 Predictions based on structural information
N4 Text mining and information extraction
N5 GO database (used in any way other than for deducing the numbers for submission)
N6 Manual annotation
Comment: free text
** The predictors are encouraged to use this section to include the description of their predictions (eg EC name, GO definition). Although this section will not be evaluated it might be useful in the case of any changes in GO codes and it will provide useful information for the next function evaluation.
Quality assessment prediction (PFRMAT QA).
Data are inserted between MODEL and END records of the submission file.
You may submit your quality assessment prediction in one of the two different modes:
QMODE 1 : global model quality score (MQS - one number for a model)
QMODE 2 : MQS and error estimate on per-residue basis.
The first line of data should specify mode identifier, i.e. QMODE (see Example 8).
In both modes, the first column in each line contains model identifier (file name of the
accepted 3D prediction).
The second column contains reliability score for a model as a whole.
The reliability score is a real number between 0.0 and 1.0 (1.0 being a perfect model).
If you don't provide MQS for a model please put "X" in the corresponding place.
If you don't want to additionally provide error estimates on per residue basis
(QMODE 1), your data table will consist of these two columns only.
If you do additionally provide residue error estimates (QMODE 2),
each consecutive column should contain error estimate in Angstroms for all the
consecutive resides in the target (i.e., column 3 corresponds to residue 1 in
the target, column 4 - to residue 2 and so on). This way data constitute a table
(Number_of_models_for_the_target) BY (Number_of_residues_in_the_target + 1).
Do not skip columns if you are not predicting error estimates for some residues -
instead put "X" in the corresponding column.
Please specify in the REMARKS what you consider to be an error estimate for a residue
(CA location error, geometrical center error, etc.).
Note. Please, be advised that a QA record line may be very long and then some
editors/mailing programs may force line wrap potentially causing unexpected parsing errors.
To avoid this problem we recommend that you split long lines into shorter sublines
(50-100 columns of data) by yourself. Our parser will consider consecutive sublines
(starting with the line containing evaluated model name and ending with the line
containing the next model name or tag END) a part of the same logical line.
END record is used for all predictions and indicates the end of a
single model submission.
Predictions of multichain targets.
Atomic coordinates should contain chain IDs as provided in template files.
In residue-residue contact predictions residue
indices should be composed of chain ID and residue number, e.g. A2, B44
(see Example 4B).
(A) An example of comparative modeling prediction. As this model is labeled UNREFINED, submission of a REFINED model is also required.
