mMass - Open Source Mass Spectrometry Tool

mMass presents open source multi-platform package of tools for precise mass spectrometric data analysis and interpretation. It is written in Python language and released under GNU General Public License, so it’s portable to different computer platforms and has a good potential to be easily modified or extended by modules of specific needs.

Feb 01, 2010 - mMass 3.0 - Comments 0

New version of mMass is finally available. I've put a lot of energy into making this program as stable and reliable as possible but you know... Please feel free to send me your comments or suggestions for further development. I hope you find the new mMass useful for your own work. Have fun...

  • Read the mMass User's Guide!
  • It is not really necessary, however, due to the small changes in colors definitions I'd recommend to use the new configuration files if you are updating from any testing version ("mMass/configs" folder under MS Windows and Linux and "~/Library/Application Support/mMass/"folder under MacOS X).
  • If you are updating from the version 2.4 or any older, please remove the old version completely.

Jan 21, 2010 - Version 3.0 RC2 released

Unfortunately, the bug in the sequence modifications as mentioned recently, were not fixed correctly. Therefore a new version is now available.

Jan 19, 2010 - Version 3.0 RC released

Release Candidate version of mMass is now available for download and testing. I hope it will be the last testing version and final mMass 3.0 will be available soon. One of the major update is mMass User's Guide describing all the mMass's features. Other changes are as follows:

  • bug fix: if a fixed modification was applied to amino acid type rather than to exact position, this modification was calculated only once, even if more amino acids of that type were presented
  • bug fix: selecting "Show specific modifications only" with no amino acid selected caused application crash
  • bug fix: "treshold" renamed to "threshold" in all configs files (an automatic update is temporarily incorporated, so you don't have to edit anything)
  • bug fix: escaping illegal characters in all config files
  • bug fix: calculation of isotopic pattern from formula containing specific isotope caused application crash
  • improved: removed "peak width" parameter from peak picking algorithm
  • improved: additional keyboard shortcuts
  • other minor fixes and improvements
