If you are mainly interested in viewing coverage, the pileup format may be
overkill, since it captures base frequencies per position.
The BowTie/TopHat source code distribution includes a program called
³wiggles² that accepts a ³SAM² format file and converts it to a ³wig² file.
I¹ve mainly looked at wiggles-generated files in Integrated Genome Browser
(bioviz.org/igb), but I¹m sure they can work fine in the UCSC browser, as
A student who works with me made a small change to ³wiggles² that lets you
run it like so:
samtools view accepted_hits.bam | wiggles > coverage.wig
If you would like him to send it to you, let me know!
