1: all overlapping and abutting intervals merged (ALL),
2: just overlapping, not abutting intervals (OVERLAPPING_ONLY),
3: no merging (NONE). This option is not currently allowed, it will throw an exception. Once we're more certain that unmerged lists are going to work in all cases in the GATK, we'll enable that.
The command line option is --interval_merging or -im
