Average Coverage of COAD/READ Data. Density plot of the average coverage for the 236 COAD/READ files. The coverage of the files varies from 2× to 8×. The tool allows for the easy identification of files with similar average coverage. The separation shown here, while less clear than in Figure 2a, is also due to use of different sequencing platforms (Illumina and SOLID) over exon data.
