## 1.0 SUMMARY

Adds secondary structure records to a DCF file (domain classification file)

## 2.0 INPUTS & OUTPUTS

DOMAINSSE parses a DCF file (domain classification file) and writes a file containing the same data, except that domain secondary structure information derived from structural are added. Domain sequences are taken from domain CCF files (clean coordinate files). The CCF files must contain secondary structure information, which can be added by using PDBPLUS. The path for the CCF files (input) and names of DCF files (input and output) are specified by the user. The extension of CCF files is specified in the ACD file. A log file is also written.

## 3.0 INPUT FILE FORMAT

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

## 4.0 OUTPUT FILE FORMAT

The format of the DCF file is described in the SCOPPARSE documentation. DOMAINRESO adds the following records:

- (1) SS - Secondary structure assignment (per residue). A simplified 3-state assignment: H (helix), E (extended, beta strand) and L (loop, open coil) is used.
- (2) SE - Secondary structure element assignment (per secondary structure element). The same 3-state assignment as for the SS record is used: H (helix), E (extended, beta strand) and L (loop, open coil).

    Adds secondary structure records to a DCF file (domain classification
    file).

The DCF file (domain classification file) lacking secondary structure information called /test_data/all.scop was parsed and a DCF file with secondary structure information called /test_data/domainseqs/all_s.scop was written. Secondary structure information was taken from CCF files in test_data/. A log file called /test_data/domainseqs/DOMAINSSE.log was written.

## 9.0 DESCRIPTION

Domain secondary structure information is not given in the raw SCOP or CATH parsable files, but is required for many analyses and for convenience should, ideally, be provided along with the classification itself. DOMAINSSE reads a DCF file (domain classificaiton file) that lacks secondary structure information and writes one containing such information.
