NAME

sambamba-flagstat - getting flag statistics from BAM file

SYNOPSIS

sambamba flagstat OPTIONS <input.bam>

DESCRIPTION

Outputs some statistics drawn from read flags.

First line contains numbers of QC-passed and QC-failed reads. Then come pairs of numbers, the former for QC-passed reads, the latter for QC-failed ones:

•

duplicates

•

mapped reads (plus percentage relative to the numbers from the first line)

•

reads with “is_paired“ flag set

•

paired reads which are first mates

•

paired reads which are second mates

•

paired reads with “proper_pair“ flag set (plus percentage relative to the numbers of QC-passed/failed reads with “is_paired“ flag set)

•

paired reads where both mates are mapped

•

paired reads where read itself is unmapped but mate is mapped

•

paired reads where mate is mapped to a different chromosome

•

the same as previous but mapping quality is not less than 5
