Validation of ComPIL with Blazmass searches using human and B. fragilis samples. a Human and B. fragilis proteins were extracted and tandem MS data was collected using MudPIT. The datasets were searched against ComPIL and either the human proteome or the B. fragilis proteome. b ComPIL searches of HEK293 cells. Unfiltered PSMs (top) and filtered PSMs (after filtering at 1 % FDR with DTASelect2, bottom) are shown categorized as forward human matches (left), forward non-human matches (middle) or reverse (e.g., decoy) protein matches (right)
