Annotates multiple Peptide Spectrum Matches (PSMs) from proteomic database search result files
Basically, the annotate_spectra
function under pylab_aux
of pyteomics (version 4.5.6) package is used iteratively over PSMs.
Raw LC-MS/MS spectra in MGF/mzML format and database search result in pepxml format needs to be provided as inputs
# Usage
> python annotatespec.py [-h] [-r ...] -p [-p ...] -i [-i ...]
Plot Annotated Peptide Spectrum Matches (PSM)
positional arguments:
-r Path to folder where DDA derived raw files (MS/MS data)are stored in mzML or mgf format
-p PSMs from database search output in pep.xml format or Prosit predicted peptide spectral library in MSP format
-i Path to PSM file from Proteome Discoverer
options:
-h, --help show this help message and exit
