@return An iterator on success; NULL on failure
Regions are parsed by hts_parse_reg(), and take one of the following forms:
region | Outputs
REF: | All reads with RNAME REF
REF:START | Reads with RNAME REF overlapping START to end of REF
REF:-END | Reads with RNAME REF overlapping start of REF to END
REF:START-END | Reads with RNAME REF overlapping START to END
. | All reads from the start of the file
| Unmapped reads at the end of the file (RNAME '*' in SAM)
The form REF: should be used when the reference name itself contains a colon.
Note that SAM files must be bgzf-compressed for iterators to work.
