WebSAMtools provides various (sub)tools for manipulating alignments in the SAM/BAM format. The SAM (Sequence Alignment/Map) format (BAM is just the binary form of SAM) is currently the de facto standard for storing large nucleotide sequence alignments. WebMay 22, 2014 · samtools flagstat prints out a host of useful stats about your mapping results, such as reads mapped. It can print a lot more information like % properly paired, # of duplicates, but it's simply relying on the information encoded in the second field of the SAM file - the bitwise flag field. WebFiltering. Most BCFtools commands accept the -i, --include and -e, --exclude options which allow advanced filtering. In the examples below, we demonstrate the usage on the query command because it allows us to show the output in a very compact form using the -f formatting option.
