Glycoscience mass spectrometry software
The MSR is developing tools for processing and analysis of proteomics and PTM data, glycan and glycopeptide mass spectral data and tools for middle-down and top down protein analysis.
GlycReSoft includes an algorithm for constructing combinatorial hypotheses glycan composition rules and combinations for N-linked and O-linked glycopeptides. This version of GlycReSoft is optimized for QTOF CAD or Q-Exactive/Orbitrap HCD data acquired using data-dependent LC-tandem MS.
Here is a GlycReSoft tutorial
