I ran the DepthOfCoverage walker with an exome bam file and supplyed it an exome bed file. In the output from the walker there is a file called *.samplestatistics. There are basically two rows one with Sourceofreads from0to1) from1to2) from2to3) and underneath it a 58835288 884725 143964. Does this file indicate I have 58,835,288 nucleotides from the exome.bed file that are covered from 0-1 times? and 884,725 covered 1-2 times?
