compareMS2

compareMS2 is a tool for direct comparison of tandem mass spectrometry datasets, typically from liquid chromatography-tandem mass spectrometry (LC-MS/MS), defining a distance as a function of the share of similar spectra. Applications span biomedicine, phylogenetics, forensics and food science.

What compareMS2 can do for you

compareMS2 calculates the similarity between tandem mass spectrometry datasets and visualizes the results in a phylogenetic tree.

  • Only mass spectrometry data is needed
  • Relative distances between samples immediately become clear
  • A Graphical User Interface simplifies usage
  • Optionally, sample files can be mapped to species names
  • Phylogenetic trees can be saved in several graphics file formats for direct use in publications
  • Input consists of MS2 data in MGF format
  • Output file formats are compatible with common phylogenetic tree software (for instance MEGA) for further processing
