pyteomics.pepxmltk - a pepXML writer and Tandem2XML converter

pyteomics.pepxmltk is a module based on the pyteomics package that allows creation of pepXML files from Python objects of a certain structure. The structure corresponds to tokens generated by the pyteomics TandemXML parser.

This package provides a module that can be used for writing pepXML files from your Python code, as well as a command-line script for conversion, merging or filtering of X!Tandem files to pepXML. Unlike its analog from Trans-Proteomic Pipeline (TPP), the script is capable of handling non-standard enzymes.
