The massXpert software package is a mass spectrometry environment for linear (bio-)polymers. It inherits all the innovations of GNU polyxmass. It allows the detailed definition of new polymer chemistries in the XpertDef module. These chemistry definitions are then used in the desktop calculator-like mass calculator (XpertCalc) and in the sophisticated polymer sequence editor and (bio-)chemical/mass spectrometric simulations module (XpertEdit). Available simulations include polymer and monomer chemical modifications, polymer sequence cleavage, gas-phase fragmentation, m/z ratio calculations, and more.

This release implements dynamic mass data filtering on the oligomer data obtained after a polymer sequence fragmentation or after arbitrary mass searches. A regression after the implementation of the previous release's features has been fixed. Minor bugs have been fixed and the code cleaned up. The GUI user experience has been improved. The documentation has been updated.
