PeptideAtlas is a multi-organism,
publicly accessible compendium of peptides
identified in a large set of tandem mass spectrometry proteomics
experiments. Mass spectrometer output files are collected for human, mouse,
yeast, and several other organisms, and searched using the latest search
engines and protein sequences. All results of sequence and spectral library
searching are subsequently processed through the
Trans Proteomic Pipeline to
derive a probability of correct identification for all results in a uniform
manner to insure a high quality database, along with false discovery rates
at the whole atlas level. Results may be queried and browsed at the
PeptideAtlas web site. The raw data, search results, and full builds can
also be downloaded for other uses.

the number of distinct peptides identified is much lower than the previous build.
