Hi Keiran, I don’t think so. As far as I know, samtools view is only used to convert (or view) SAM<->BAM<->CRAM. However, the file must not be sorted, while indexing implies that the file is sorted. I’d use ‘samtools view’ to convert the file if necessary, sort it using ‘samtools sort’ and then ‘samtools index -c’ to index the resulting file.

Hi, Is it possible to write a csi index when using samtools view? I can't see anything in the --output-fmt* section relating to index format.
