 The massXpert project aims at providing (bio)chemists with a software
 package allowing the following:
 
 * User-specific atom definitions and polymer chemistry definitions;
 * Powerful sequence editing with user-defined glyphs for each monomer
 and monomer chemical modification. Multi-region selections;
 * Polymer sequence chemical/enzymatic cleavage;
 * Intramolecular cross-linking, like disulfide bonds with total resolution
 of the peptides generated upon enzymatic cleavage;
 * Gas-phase fragmentation of oligomers;
 * Mass-to-charge ratio calculations with inline change of ionization agent;
 * Calculation of net electrical charge and of isoelectric point (even by
 taking into account monomer modifications if polymer is a protein);
 * Simulation of isotopic patterns for any chemical formula and z charge;
 * A number of plugins allow 1) translation of the sequence from one format
 to another (using a dictionary, like between the 1-letter code and the 3-letter
 code of proteins) 2) conversion of number format according to any localized
 number format 3) sort mass lists.
