  1. Given are the sequence pool name (column 1) and sequence with the highest frequency of occurrence (column 2); the frequency of occurrence (FO) of this peptide in the according pool (column 3), the FO in the pool containing all sequences except the one of the analyzed pool (column 4), the FO in the pool containing all sequences generated by the same strategy (GBSS) excluding sequences of the analyzed pool (column 5). Italic shows peptides with at least 50-fold higher frequency with respect to all (column 4) or peptides of the same strategy (column 5). Hashtag after the pattern indicate 500-fold higher frequency in at least column 4 or column 5
