From: Rapid evaluation and quality control of next generation sequencing data with FaQCs
Boxplot graph for the quality scores. Rectangular boxes show the Inter-quartile Range (IQR). The end of the whiskers shows outliers at max 1.5*IQR. Horizontal lines in the box are median values at each bp position. There is a horizontal line at quality 20 indicating the predicted per base error rate of 1/100. For easy comparison, FaQCs generates two boxplots side by side where the left panel is the boxplot of the raw reads and the right represents the processed reads. This is but one set of figures generated in the final PDF report (see Additional file 1: Figure S1).
