MS-Virtmorph

Virtual Polymorphism Database Generator for finding new matches in your peptide MS/MS data.

Use this tool to impose statistically and biologically likely amino acid substitutions ("virtual polymorphism") on your amino acid sequence entry and make a database to re-interrogate your MS or MS/MS data.
