I am trying to replicated Hendrik Weissers MHC Workflow, with a few changes.
Basically the workflow is as follows:
- Detection with MSGFPlus, annotation with PeptideIndexer
- Alignment mit MapAlignerIdentification followed by MapRTTTransformer
- Merging of the aligned idXML files with ID merger
After this step, I would like to apply Percolator to the merged idXML file (as in the MHC Workflow), however, PSM FeatureExtractor throws following error:
error: Unexpected internal error (the element No accession found in run for PSM . Please contact the maintainer of this tool e.g. on GitHub as this should not happen." could not be found.
Any ideas what is going on here ?
thanks a lot,
