WebAnswer: You can identify the unmapped reads using the flags from column 2 in in the BAM file. These flags are described in the SAM/BAM specification here. The flag identifying an un-mapped read is the number 4. But if you only took the BAM entries with a 4 in column 2 you would miss some unaligned reads. This is because BAM flags are additive.
