Minor size differences in output bam file
Hi @FelixKrueger I have three bam outputs generated with identical parameters and identical versions of Bismark and bowtie2 using a set of paired end trimmed inputs. Three parallel parameters were used- 8, 12 and 16. The total no. of reads aligned to the genome according to their respective alignment reports are the same.
However, the bam files have a size difference. See below. What could cause these size differences?

- 12; 86250282377
- 8; 86111223110
