WebUsing the -d option, bedtools genomecov will compute the depth of feature coverage for each base on each chromosome in genome file provided. The “per-base” output format is as follows: chromosome chromosome position depth (number) of features overlapping this chromosome position. For example: WebSAM Tools provide various utilities for manipulating alignments in the SAM format, including sorting, merging, indexing and generating alignments in a per-position format. SAMtools is hosted by GitHub. The project page is here. The source code releases are available from the download page. You can check out the most recent source code with:
