[Psidev-ms-dev] HUPO-PSI: edited mzPAF specification v1 draft 04 - 14-day public review until April 10th, 2026

[ricard-blum s. <syl...@un...>]

Dear colleagues, dear members of the HUPO-PSI community,

The HUPO Proteomics Standards Initiative (PSI) develops standards  for 
documentation and storage of proteomics, glycomics and interaction data 
(see http://www.psidev.info for an overview of activities).

The Mass Spectrometry and Proteomics Informatics Working Groups have 
submitted a corrected version of the mzPAF (Peak Annotation Format) 
specification which was released on September 22nd, 2025. They  updated 
the x-ion formula, fixed some reference ion formulas/masses and added 
one contributor and precision about spectra acquired in the negative ion 
mode.

This amended document has been reviewed by two members of the Steering 
Group. Given that it has been submitted within 12 months after the 
acceptance and that very minor changes were made, the document now goes 
through a 14-day public review, which should end on April 10th, 2026 in 
agreement with the PSI Document Process.

The version 1, draft 04 of the specification is attached to this e-mail 
and is also available at https://www.psidev.info/mzpaf.

This message is to encourage you to contribute to the standards 
development activity by commenting on the document. We invite both 
positive and negative comments on the relevance, correctness, clarity 
and appropriateness of the specification. Comments can be made on the 
specification as a whole or on specific parts.
If you do not feel experienced enough to comment on this document, but 
know colleagues who are, please feel free to forward this message to 
them. There is no requirement that people commenting should have had any 
prior contact with the PSI.

Please send comments by e-mail to syl...@un... 
before*April 10th, 2026*.

I thank you very much in advance for your contribution and time.

Kind regards.
