2.Description and objectives


Focus and Purpose


The PSI-QC working group is composed of academic, government, and industry researchers, software developers, journal representatives, and instrument manufacturers. The main goal of the PSI-QC working group is to define a community data format and associated controlled vocabulary terms, facilitating data exchange and archiving of mass spectrometry derived quality control metrics.

Current projects of the PSI-QC working group are:

  • The mzQC format, which is emerging as a standardized JSON format for the exchange, transmission, and archiving of quality control metrics derived from mass spectrometry.
  • Controlled Vocabulary development: controlled vocabulary terms are developed in common with the PSI-MS and PSI-PI groups.





  1. submit a perspective manuscript to a journal in the field to announce the PSI-QC WG √ (PubMed link)
  2. analyze and revise the mzQC format for submission to the PSI document process √ 
  3. re-evaluate the CV terms used for mzQC, and consolidate the location for these terms in light of the existing PSI-MS CV √ 
  4. adapt the already published jqcML library to handle mzQC JSON streams in addition to mzQC links for relevant CV terms with validation
  5. implement mzQC output from several freely available quality metric tools (e.g., QuaMeter, OpenMS)
  6. establish the revised mzQC format and associated CV terms as a HUPO-PSI standard by submitting the standard to the PSI Document Process
