[0.3.1] - 2023-06-19

Changed

  • io.sage: Change spectrum_fdr to spectrum_q (crf. lazear/sage#64).

[0.3.0] - 2023-06-08

Added

  • Add reader for Sage PSM files.

  • io.mzid: Add reading/writing of PEP and q-values

Changed

  • psm: The default values of PSM.provenance_data, PSM.metadata and PSM.rescoring_features are now dict() instead of None.

  • PSMList: Also allow Numpy integers for indexing a single PSM

  • io.mzid.MzidReader: Attempt to parse retention time or scan start time cvParams from both SpectrumIdentificationResult as SpectrumIdentificationItem levels. Note that according to the mzIdentML specification document (v1.1.1) neither cvParams are expected to be present at either level.

  • io.mzid.MzidReader: Prefer spectrum title cvParam over spectrumID attribute for PSM.spectrum_id as these titles always match to the peak list files. In this case, spectrumID is saved in metadata["mzid_spectrum_id"]. Fall back to spectrumID if spectrum title is absent.

  • io.mzid.MzidWriter: PSM.retention_time is now written as cvParam retention time instead of scan start time, and to the SpectrumIdentificationItem level instead of the SpectrumIdentificationResult level, as theoretically in psm_utils, multiple PSMs for the same spectrum can have different values for retention_time.

  • io.percolator.PercolatorTabWriter: For PIN-style files: Use SpecId instead of PSMId and write PSMScore and ChargeN columns by default.

  • Filter warnings from psims.mzmlb on import, as mzmlb is not used

Fixed

  • psm: Fix missing qvalue and pep in docstring

  • peptidoform: ProForma mass modifications are now correctly parsed within the rename_modifications function.

  • io.maxquant.MSMSReader: Correctly parse empty Proteins column to None

  • io.percolator.PercolatorTabReader: Correctly parse Percolator peptidoform notation if no leading or trailing amino acids are present (e.g. .ACDK. instead of K.ACDK.E).

  • io.percolator.PercolatorTabWriter: ScanNr is now correctly written as an integer counting from the first PSM in the file.

  • io.percolator.PercolatorTabWriter: If no protein information is present, write the peptidoform preceded by PEP_ to the Proteins column.

  • io.idxml: Read metadata as strings

  • io.mzid.MzidReader: Set PSM.retention_time to None instead of float('nan') if missing from the PSM file.

  • io.mzid: Fix reading of file if charge is missing

  • io.mzid: Fix writing if protein_list is None

  • io.mzid: Consider all PeptideEvidence entries for a SpectrumIdentificationItem to determine is_decoy
