This program takes a list of protein domains (ie. a LISTFILE) and
outputs a series of sequences derived from the described PDB
files. The format is:
pdbseq -f <domain file> [-min <val> -max <val> -foramt <fasta>]
`-min/max <val>' specify the minimum/maximum sequence length to be output. If the length of a sequence is less than min or greater than max, the sequence will be skipped (useful particularly if one wants to ignore very short PDB sequence, such as peptide inhibitors, etc.). The output is in NBRF (PIR) format, and is written to the standard output. Using `-format <fasta> will make the output as FASTA format.
