The HPP aims to encourage all participants/authors to uphold rigorous 
standards for publication and dissemination of results. All data are to 
be submitted to a ProteomeXchange public data repository, statistical 
analyses are to be performed to a high standard, and claims of detection
 of "missing proteins" or novel coding elements require detailed 
evidence. The first set of HPP data interpretation guidelines were 
approved by the HPP in 2012. Version 2.0 of the guidelines was approved 
in 2015, and a minor substantive update was applied as version 2.1 in July
2016.  A Version 3.0 of the guidelines was released in 
October 2019. These newest guidelines should be applied to all 
subsequent manuscripts and data contributions from release.
IMPORTANT NOTE: If your manuscript is being submitted to JPR for the HPP special issue, the JPR guidelines also apply. In cases where the JPR guidelines and these HPP guidelines conflict, the HPP guidelines are more stringent in all cases and take precedence over the JPR guidelines. See the Current JPR Guidelines.
 
2016 Guidelines (Deprecated):
- 
    Obsolete HPP Data Interpretation Guidelines version 2.1 [PDF] - 2016-07-28
 
 
- 
    Changelog:
 Version 2.1 has been updated in response to the review of the 
manuscript accompanying these guidelines. Guideline 2 has been altered 
such that deposition of data in a ProteomeXchange repository must now 
occur prior to submission of a manuscript rather than prior to review of
 the manuscript. Guideline 15 was updated to clarify that the two 
uniquely mapping peptides of length >=9 amino acids may not be fully 
nested (i.e. one peptide occurring within the other). This was 
previously intended and implemented in neXtProt and PeptideAtlas, but 
was not explicit in the checklist.
