Percolator

note

Semi-supervised learning for peptide identification from shotgun proteomics datasets

https://github.com/percolator/percolator

The module assumes that the Percolator output file is named *percolator_feature_weights.tsv. Make sure to run it using:

percolator ... > samples.percolator_feature_weights.tsv

The module accepts one configuration option:

  • group_to_feature: A dictionary mapping group names to feature names (empty per default), e.g. in multiqc_config.yaml:
percolator:
  group_to_feature:
    psm_file_combined: [MS:1002255, MS:1002252]
    ms2pip: [ionb_min_abs_diff, iony_min_abs_diff]
    deeplc: [rt_diff]
