DESCRIPTION

ssematch

is a command line program from EMBOSS ("the European Molecular Biology Open Software Suite"). It is part of the "Utils:Database creation" command group(s).

OPTIONS

Input section

-ssinfile infile

This option specifies the name of the file of secondary structure (input).

-dcfinfile infile

This option specifies the name of the 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.

-datafile matrixf

This option specifies the secondary structure substitution matrix. Default value: SSSUB

Required section

-maxhits integer

This option specifies the number of top-scoring matches to report. Default value: 5

Additional section

-gapopenr float

This options specifies the gap insertion penalty for reside-based alignment. The gap insertion penalty is the score taken away when a gap is created. The best value depends on the choice of comparison matrix. The default value assumes you are using the EBLOSUM62 matrix for protein sequences, and the EDNAFULL matrix for nucleotide sequences. Default value: 10

-gapextendr float

This options specifies the gap extension penalty for residue-based alignment. The gap extension, penalty is added to the standard gap penalty for each base or residue in the gap. This is how long gaps are penalized. Usually you will expect a few long gaps rather than many short gaps, so the gap extension penalty should be lower than the gap penalty. Default value: 0.5

-gapopene float

This options specifies the gap insertion penalty for element-based alignment. The gap insertion penalty is the score taken away when a gap is created. The best value depends on the choice of comparison matrix. The default value assumes you are using the EBLOSUM62 matrix for protein sequences, and the EDNAFULL matrix for nucleotide sequences. Default value: 10

-gapextende float

This options specifies the gap extension penalty for secondary structure element-based alignment. The gap extension, penalty is added to the standard gap penalty for each base or residue in the gap. This is how long gaps are penalized. Usually you will expect a few long gaps rather than many short gaps, so the gap extension penalty should be lower than the gap penalty. Default value: 0.5

Output section

-outssfile outfile

This option specifies the name of the file containing top-scoring domains for residue-based alinnment (output).A 'domain classification file' contains classification and other data for domains from SCOP or CATH, in DCF format (EMBL-like).

-outsefile outfile

This option specifies the name of the file containing top-scoring domains for secondary structure element-based alinnment (output). A 'domain classification file' contains classification and other data for domains from SCOP or CATH, in DCF format (EMBL-like).

-logfile outfile

This option specifies the name of the ssematch log file (output). Default value: ssematch.log
