Peptide identification from mass-spectrometry data

This workflow performs a simple peptide identification from mass-spectrometry experiments (in mzML format). It matches fragment spectra against theoretical spectra from a protein database and visualizes the results interactively in a table together with a spectrum viewer.
Potential input data can be found under Links. Save the files as mzML and fasta and configure the Input File nodes to read them from your disk.
