1.0 SUMMARY

Remove low resolution domains from a DCF file


2.0 INPUTS & OUTPUTS

DOMAINRESO reads a DCF file and writes a DCF file containing the same domains excluding those whose resolution (Angstrom) of structure determination exceeds a user-defined threshold. The resolution data are taken from CCF (clean coordinate files) whose path and file extension (via the ACD file) are specified by the user. The names of the input and output files are also specified by the user.


3.0 INPUT FILE FORMAT

The format of the DCF file is described in the SCOPPARSE documentation.

5.0 DATA FILES

DOMAINRESO does not use any data files.


6.0 USAGE

6.1 COMMAND LINE ARGUMENTS

Remove low resolution domains from a DCF file.
Version: EMBOSS:6.4.0.0

   Standard (Mandatory) qualifiers:
  [-cpdbpath]          dirlist    [./] This option specifies the location of
                                  domain CCF file (clean coordinate files)
                                  (input). A 'clean cordinate file' contains
                                  coordinate and other data for a single PDB
                                  file or a single domain from SCOP or CATH,
                                  in CCF format (EMBL-like). The files,
                                  generated by using PDBPARSE (pdb files) or
                                  DOMAINER (domains), contain 'cleaned-up'
                                  data that is self-consistent and
                                  error-corrected. Records for residue solvent
                                  accessibility and secondary structure are
                                  added to the file by using PDBPLUS.
  [-dcfinfile]         infile     This option specifies the name of DCF file
                                  (domain classification file) (input). A
                                  'domain classification file' contains
                                  classification and other data for domains
                                  from SCOP or CATH, in DCF format
                                  (EMBL-like). The files are generated by
                                  using SCOPPARSE and CATHPARSE. Domain
                                  sequence information can be added to the
                                  file by using DOMAINSEQS.
   -threshold          float      [2.8] This option specifies the threshold
                                  for inclusion (Angstroms). Domains exceeding
                                  the threshold for inclusion (Angstroms)
                                  will not be given in the output file. (Any
                                  numeric value)
  [-dcfoutfile]        outfile    [test.scop] This option specifies the name
                                  of DCF file (domain classification file)
                                  (output). A 'domain classification file'
                                  contains classification and other data for
                                  domains from SCOP or CATH, in DCF format
                                  (EMBL-like). The files are generated by
                                  using SCOPPARSE and CATHPARSE. Domain
                                  sequence information can be added to the
                                  file by using DOMAINSEQS.

6.2 EXAMPLE SESSION

An example of interactive use of DOMAINRESO is shown below. Here is a sample session with domainreso


% domainreso 
Remove low resolution domains from a DCF file.
Clean domain coordinates directories [./]: ../domainer-keep/
Domain classification file: ../scopparse-keep/all.scop
Threshold for inclusion (Angstroms). [2.8]: 2.3
Domain classification output file [test.scop]: all_2.3.scop

/homes/user/test/qa/domainer-keep/d1cs4a_.ccf
/homes/user/test/qa/domainer-keep/d1ii7a_.ccf

Go to the input files for this example
Go to the output files for this example



The following command line would achieve the same result.
 
domainreso /test_data /test_data/all.scop /test_data/domainreso/all_2.3.scop -threshold 2.3



7.0 KNOWN BUGS & WARNINGS

No known bugs.


8.0 NOTES

Domains that lack a value for resolution in the CCF file (e.g. theoretical models and NMR structures) are included in the output file.

8.1 GLOSSARY OF FILE TYPES

FILE TYPE FORMAT DESCRIPTION CREATED BY SEE ALSO
Domain classification file (for SCOP) DCF format (EMBL-like format for domain classification data). Classification and other data for domains from SCOP. SCOPPARSE Domain sequence information can be added to the file by using DOMAINSEQS.
Domain classification file (for CATH) DCF format (EMBL-like format for domain classification data). Classification and other data for domains from CATH. CATHPARSE Domain sequence information can be added to the file by using DOMAINSEQS.
Clean coordinate file (for domain) CCF format (EMBL-like format for protein coordinate and derived data). Coordinate and other data for a single domain from SCOP or CATH. The data are 'cleaned-up': self-consistent and error-corrected. DOMAINER Records for residue solvent accessibility and secondary structure are added to the file by using PDBPLUS.
None


9.0 DESCRIPTION

It is desirable to omit poor resolution protein structures when performing certain analyses of protein domains. DOMAINRESO reads a DCF file (domain classification file) and writes one containing the same domains excluding those whose resolution (Angstrom) of structure determination exceeds a user-defined threshold.


10.0 ALGORITHM

None.
