Hi, I'm trying to index a huge BAM file (~180 GB) in anticipation of
converting it to SAM. I tried running
>> samtools index file.bam
but it got killed, most likely because my computer ran out of RAM. Can
someone give me a ballpark estimate of how much memory is needed to index a
BAM file as a function of the BAM file's size? Correspondingly, what sort
of memory requirements should I anticipate in order to convert the indexed
BAM file to a sorted SAM file?
Thanks,
-Irena
