**What it does**

Produces a tabular description of peptides resulting from theoretical
digest of a given protein database by the selected enzyme agent using
the digestdb program distributed with the Transproteomic Pipeline.

** Output **

 Results are spit out to stdout in a tab-delimited format.

 Asterisks (*) in sequence are treated as proper break points

 Output columns:
 - peptide length
 - protein reference
 - peptide mass
 - previous amino acid before peptide
 - peptide sequence
 - next amino acid after peptide
 - peptide start location
 - peptide end location
 - pI
