The massXpert software package is a massspectrometry environment for linear(bio-)polymers. It inherits all the innovations ofGNU polyxmass. It allows the detailed definitionof new polymer chemistries in the XpertDef module.These chemistry definitions are then used in thedesktop calculator-like mass calculator(XpertCalc) and in the sophisticated polymersequence editor and (bio-)chemical/massspectrometric simulations module (XpertEdit).Available simulations include polymer and monomerchemical modifications, polymer sequence cleavage,gas-phase fragmentation, m/z ratio calculations,and more.License: GNU General Public License (GPL)Changes:
This release implemented a new fragmentation specification method for fragmentation patterns where the monomer undergoing fragmentation has its lateral chain decomposed. This is particularly useful in nucleic acids chemistry where the nucleic base might be eliminated at the monomer undergoing fragmentation according to the pattern 'a'. The French translation was updated. A memory leak and bugs were fixed. The user manual was updated.
