I cannot prepare MacOSX packages anymore as I have no more a MacOSX computer at my disposal. If anyone wants to donate a Mac computer, I'll resume package creation. Thank you.

  • 2012 12 25 New release, version 3.4.0.

  • 2011 10 22 New release, version 3.2.0. Update: Debian GNU/Linux users: a debugging symbols package will be available soon, as package massxpert-dbg;
  • 2011 06 05 Performed my first debian package upload as a Debian Developer !
  • The packages for MS-Windows and MacOSX no more ship the user manual. Please download it from the website.
  • Publication of massXpert in the prestigious british journal Bioinformatics, UK. See News (Section July)!

massXpert is about mass spectrometry.

This is software that runs on MS-Windows, Apple-Mac-OS-X, GNU-Linux, and almost all variants of the UNIX system.

With massXpert you actually have four programs in one :

  1. With the XpertDef module you define brand new polymer chemistries (what are the atoms, what are the monomers that make the polymer, what are the chemical modifications that you might need to simulate biological or synthetic chemical reactions, what are the different ways you might need to cut a polymer sequence into pieces (chemical or enzymatic), what are the different ways that a small oligomer might fragment in the mass spectrometer's gas phase, and so on...

  2. With the XpertCalc module, you get a desktop calculator that understands your polymer chemistry definitions as defined in XpertDef. The calculator allows any kind of chemical reaction and is infinitely programmable. Any calculation is recorded in a logbook that is exportable to put in the lab-book;

  3. With the XpertEdit module, you get a sophisticated polymer sequence editor and a chemical center where a huge amount of simulations might be performed. Anything mass-related is virtually feasible in XpertEdit.

  4. With the XpertMiner module, you will get (it is being implemented) a data mining center. You'll be able to drag and drop data from the mass spectra (in the form of m/z lists) and data from the simulations performed in the XpertEdit module. Once there, all the data will be available for comparison, arbitrary calculations like, say : "this list of m/z values should be applied the following mass increase" or "this list of m/z values should be appplied this reaction: -H+Na". The possibilities should be infinite.
