Expected errors in the Saccharomyces PeptideAtlas are calculated for four cases and lower probability limits (Plimit = 0.9, 0.95, 0.99): the assigned probability P of each MS/MS is used for all Pi ≥ Plimit; the assigned probability P of each MS/MS is used for all Pi ≥ Plimit where the associated peptide has been seen in the S. cerevisiae PeptideAtlas more than once'; the best probability for each unique peptide sequence is used for all Pi ≥ Plimit; the best probability for each unique peptide sequence is used for all Pi ≥ Plimit when the peptide has been seen in the S. cerevisiae PeptideAtlas more than once. |
