[Bioperl-l] Perl Regular Expressions sought that match typical

[M.Shahid]

Dear All,
For a small software project, I'm looking for Perl Regular
Expressions that match file formats and related input used
for bioinformatics applications, e.g. FASTA, Clustal, 
PROSITE patterns, PAM similarity matrices, etc. Note 
that I do not want to parse such data, just check whether 
the format is correct. Is there any compilation out there ? 
If not, what is the best starting point to collect such Regular 
Expressions ?

Best Wishes,

M. Shahid
