massXpert 3.4.0

With Massxpert You Actually Have Four Programs In One :

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...

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;

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.

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.

History updates (Complete changelogs since the listing on this site)

3.4.0 [12-31-12]

>Implemented a feature that allows one to enter a coordinates string in the sequence editor window so as to select a specific sequence, make a multi-region selection, or make a multi-selection region;

The mzLab GUI has been refactored so as to greatly simplify its use;

The French translation has been updated.

Other versions : 3.3.0 3.2.0 3.1.0 3.0.0 2.8.0 2.5.2 2.5.0 2.4.3 2.4.2 2.4.0 2.3.6

v3.3.0 [12-06-12]

>Implemented new ways to share mass data between the three main simulations contexts (polymer cleavage, oligomer fragmentation and arbitrary mass searches, of within the XpertEdit module) and the MzLab in the XpertMiner module. Also, it is now possible to first export the data from the three simulations contexts to either a file or the clipboard, to crunch the data in any way and format these data so as to reimport them in the XpertMiner module. An a posteriori connnection is now possible between the reimported data and the polymer sequence that generated these data in the first place by providing the MzLab with the identifier of the polymer sequence editor in which the proper polymer sequence has been loaded. This allows for maximum flexibility when analyzing the data, such that it is possible at any time to visualize the corresponding oligomer in the sequence editor upon clicking on any mass list item of the MzLab. All this is documented in the massXpert.pdf user manual.

v3.2.0 [10-25-11]

>Implemented new feature by which it is now possible to account for cross-links when simulating oligomer fragmentations. Only cross-links that involve monomers all contained in the fragmenting oligomer are taken into account.

v3.1.0 [09-06-11]

>Improvements in the XpertMiner module that make working with lists easier;

Fixed calculation bug which appeared when computing the isotopic cluster of a large polymer with low resolution... the peak shape would not be centered in the average centroid value.

Added a full spectrum simulation feature that allows one to compute a spectrum (optionally with all the isotopic clusters) on the basis of a list of oligomers obtained by cleavage of a given polymer;

Same as above but after computing a set of m/z ratios starting from a chemical formula;

Updated the user manual to document a number of new features since last update.

v3.0.0 [08-02-11]

>Changed the mass search oligomer display from a tree view to a table view which is simpler, both programmatically and functionally (for the user). That fixes a bug that would occasionally crash the software.

v2.8.0 [07-15-11]

v2.5.2 [06-18-11]

>Fix to critical regression bug introduced in version 2.5.1 which made the program crash in any kind of oligomer fragmentation.

v2.5.0 [05-26-11]

>Added feature : ability to select -H20 and -NH3 (also to set a manually-defined formula) as additional decompositions to be handled while computing fragment oligomers.

v2.4.3 [02-21-11]

>Added feature: when running the mz calculations dialog from the sequence editor window, the masses are automatically set in the dialog window.

Added ion charge proton to the formula of the z fragmentation specification.

Rewrote the Formula's elementalComposition() so that the order of the atoms is in the CHNO->alphabetic conventional order.

v2.4.2 [01-28-11]

>Fixed a bug that crashed the program when the user would click (on the sequence editor) left of first monomer vignette.

v2.4.0 [01-06-11]

>Fixed a problem with considering that the lightest isotope was necessarily the most abundant isotope. In fact this is true for the main chemical elements in biological matter, but can be not true for other chemical elements. This fix will only matter to people using chemical elements of which the most abundant isotope is not the lightest one.

v2.3.6 [07-07-10]

>Added an alert that triggers itself when the user tries to cleave a polymer sequence region that does not encompass all the cross-linked monomers, as this would yield non faithful oligomers;

Fixed a small GUI bug in the sequence editor;

Fixed a linker flag in the build of massXpert for the PPC platform (thanks to Koen van der Drift of the Fink project).
