Hi, I am the developer and maintainer of massypup64, a live system for data analysis, workflow creation and data mining of mass spectrometry data (http://www.bioprocess.org/massypup/). One of the example workflows on the system analyses mzML files with comet (target-decoy) and following performs a hit validation with the  TPP Prophet scripts. The workflow is set up in taverna and creates output in various file formats (for details: https://peerj.com/articles/1401/). Unfortunately, the mzid files are not recognized as result files in ProteomeXChange submission. Any idea, how to generate a valid mzid file from the mzML, pep.xml, prot.xml, fasta files? Ideally, with a command line program/ script (bash, python, Perl, java, R,.. Open Source). 

Thanks, Robert
