Ms-Unimod allows easy setup of a Unimod database (using Sqlite) that
can be used to calculate the masses of peptides with modifications.
http://mspire.rubyforge.org/projects/ms-unimod/
== Usage
First generate the Unimod database:
% tap generate unimod_db
Then use the pepmass task to calculate a peptide mass, with or without
n- or c-term modifications:
% tap run -- pepmass :RPPGFSPFR: --: dump
% tap run -- pepmass Acetyl:RPPGFSPFR:Hydroxyl% --: dump
== Installation
Ms-Unimod is available as a gem on RubyForge. Use:
% gem install ms-unimod
