Hi, Burak.

You shouldn't need to subset the BAM file into regions.  IGV will load
HUGE BAM (we have loaded 200x coverage human genome) files without a
problem since it reads only the part of the file necessary and does
not store large files in memory.  And you will definitely want to use
BAM and not SAM for IGV.
