Table 2.
Number of analyzed Homo sapiens peptides from various spectral libraries. A consensus peptide may appear more than once in a given spectral library. The second column lists the total number of consensus peptides (with redundancy) within each library. The third column shows the total number of consensus peptides (with redundancy) that have combined E-values less than 10−3 assigned by RAId_aPS. The non-redundant version of this column is recorded in the fourth column. Due to the inter-library redundancy, the total number, 271,557, of nonredundant consensus peptides is smaller than the sum from that of each library. These 271,557 nonredundant consensus peptides were labeled proteotypic in RAId’s Homo sapiens database.
