The Global Proteome Machine Organization
   The GPMDB Project

The Generalized Proteoform Meta-analysis Database was constructed to utilize the information obtained by GPM servers to aid in the difficult process of validating peptide MS/MS spectra as well as protein coverage patterns. This database has been integrated into the GPM server pages, allowing users to quickly compare their experimental results with the best results that have been previously observed by users of the machines.

Every effort has been made to anonymize the results used by the gpmDB. If you do not wish your data to be made available in this way, please be sure to click the appropriate box on the search pages.

   gpmDB: Design

gpmDB was designed to be a simplification and extension of the MIAPE scheme proposed by the PSI committee of HUPO. Rather than being a complete record of a proteomics experiment, this database holds the minimum amount of information necessary for certain bioinformatics-related tasks, such as sequence assignment validation. Most of the data is held in a set of XML files: the database serves as an index to those files, allowing for very rapid lookups and reduced database storage requirements. We call this combination of a relational database with XML data XIAPE (Xml Information About a Proteomics Experiment).
