Hello all,

I used MarkduplicatesSpark and at the end i obtained a bam splitting index (.sbi). I search on internet but i don't really found what it is exactly and if it's really mandatory ?

Thanks in advance 😀

SBI is an index into BGZF-compressed data files, which has an entry for the file position of the start of every nth record.

it allows to split the job in n-parts for Spark
