ps_scan (ScanProsite tool) is a perl program used to scan one or several patterns, rules and/or profiles from PROSITE against one or several protein sequnces in Swiss-Prot or FASTA format. It requires two compiled external programs from the PFTOOLS package : “pfscan” used to scan a sequence against a profile library and “psa2msa” which is necessary for the “-o msa” output format only.
