From Array Suite Wiki
A BAM file (.bam) is the binary version of a SAM file that contains sequence alignment data.
Genome Browser Track
The OmicSoft Genome Browser can directly load and display .bam files from your local computer, ArrayServer, or ENCODE. In addition to a Genome Coverage track, users can optionally display exon junctions, variation, profiles of read mapping, and nucleotide sequence for each read. Hovering your mouse over a read will display information about that read.
