Figure 3. ROC comparison of performance.

Figure 3

ROC curves showing the performance of τr, computed using the spectral count (dotted) and ion abundance (solid) measures, in characterizing the relative abundance of proteins in Mix 1 and Mix 2 of the BIATECH-54 set across the species, peptide and protein rollup levels. (a) shows the results obtained using the data searched for fully-tryptic species, and (b) for semi-tryptic species. The AUC corresponding to each curve is shown in parenthesis.
