Fig. 5From: Evaluation of open search methods based on theoretical mass spectra comparisonColor classification and LIPR for Strategy2 (\(\hbox {PSM}_2\)). Number of PSMs in the three color categories and average LIPR according to minimum shift SPC (left). Percentage of PSMs in the three color categories (Green: solid line, Orange: dotted and dashed line, Red: dashed line) according to shift SPC (right). The vertical line is located at FDR < 1% (shift SPC = 21)Back to article page
