Comparison of the number of PSMs among various databases of typical sizeĀ and number of target and decoy unique peptides. a, b, c The blue bars show the numbers of PSMs for 1% FDR without the correction factor. The orange bars show the numbers of PSMs for 1% FDR using Factor 2. The gray bars show the numbers of PSMs for 1% FDR using Factor 1. The yellow line show the ratio of target and decoy unique peptide ratio. a The UniProt S. cerevisiae protein database and the S. cerevisiae Elite dataset. b The UniProt human protein database and the HEK293 3-replicate dataset. c The UniProt human protein database and the HEK293 24-fraction dataset. d The blue bars show the ratios of all peptides to unique peptides. The red bars show the ratios of all peptides to redundant peptides. Comparison of the ratio of unique and redundant peptides for the S. cerevisiae and human protein databases
