mMass - Open Source Mass Spectrometry Tool

Program mMass presents an open source multi-platform package of simple tools for mass spectrometric data analysis. It consist of several modules and tools for protein sequence handling and mass spectrum interpretation with focus on common proteomic tasks. As the program is written in Python language, uses wxPython libraries for graphic user interface and is released under GNU General Public License, it is portable to many computer platforms and has a good potential to be easily modified or extended by modules of specific need.

Finally I have made a simple user's guide available for all the mMass users. Hopefully it will be useful for you.

10/04/07 - Version 2.4 released - [6 comments]

New version has been released and is now available in download section. Major improvements are as follows:

  • New panel-view for Protein Digest and Peptide Fragmentation tools to list, filter and export calculated values. Any value selected in the list is automatically highlighted in the spectrum.
  • New panel for spectrum view options (Alt+S).
  • Gel-view height can be set in the spectrum view options.
  • Sequence import filter improved.
  • Selected peak in calibration dialog is highlighted in the spectrum.
  • Select All Annotated Peaks.
  • Print report improved.
  • Increased number of missed cleavages to 50.
  • Increased length of peptide for fragmentation to 100.
  • Current file name is used as a title for Mascot search.
  • Current file name is used for export spectrum or peaklist.
  • Check for updates in Help menu
  • Drag files to list of Loaded Spectra to add spectra (Mac only)
  • Drag files to list of Loaded Peaklists to add peaklist (Mac only)

  • Zoom spectrum selection by Ctrl+LMB (usefull for one-button mouse).
  • Scroll and scale factors can be set in config.ini.
  • Show/hide spectrum grid.
  • Digest peptides can be exported by right clicking on the list.
  • Instruments presets for peptide fragmentation.
  • Value of position/distance can be shown at cursor position under Mac OS X too.
