polymer chemistry modelling and mass spectrometry data simulation (data)

 massXpert allows the user to perform the following tasks:
 .
  - Make brand new polymer chemistry definitions;
  - Use the definitions to easily perform calculations in a desktop
    calculator-like manner;
  - Perform sophisticated polymer sequence editing and simulations;
  - Perform m/z list comparisons;
 .
 Chemical simulations encompass cleavage (either chemical or
 enzymatic), gas-phase fragmentations, chemical modification of any
 monomer in the polymer sequence, cross-linking of monomers in the
 sequence, arbitrary mass searches...
 .
 This package ships the polymer chemistry data.
