When you publish next gen sequencing data you have to include the percent reads aligned. The number is easy to get but when you have 200+ samples it’s a pain to collate them together. This script takes a directory with bam files, uses samtools flagstat to get percent reads aligned and then does a little rejiggering of format to put it in a nice list. To run it, enter the directory with the bams and type ‘bash ./percent_counter.bash’

percent_counter.bash NOTE: The script is gzipped.
