Usage: sga merge [OPTION] ... READS1 READS2 Merge the sequence files READS1, READS2 into a single file/index -v, --verbose display verbose output --help display this help and exit -t, --threads=NUM use NUM threads to merge the indices (default: 1) -p, --prefix=PREFIX write final index to files starting with PREFIX (the default is to concatenate the input filenames) -r, --remove remove the original BWT, SAI and reads files after the merge -g, --gap-array=N use N bits of storage for each element of the gap array. Acceptable values are 4,8,16 or 32. Lower values can substantially reduce the amount of memory required at the cost of less predictable memory usage. When this value is set to 32, the memory requirement is essentially deterministic and requires ~5N bytes where N is the size of the FM-index of READS2. The default value is 4.
