Number of PSMs in the three color categories and average LIPR according to minimum raw SPC (left). Percentage of PSMs in the three color categories (Green: solid line, Orange: dotted and dashed line, Red: dashed line) according to raw SPC (right). The vertical line is located at FDR < 1% (raw SPC = 17)Back to article page
