	"Usage: wtpoa-cns [options]\n"
	"Options:\n"
	" -t <int>    Number of threads, [4]\n"
	" -d <string> Reference sequences for SAM input, will invoke sorted-SAM input mode\n"
	" -u <int>    XORed flags to handle SAM input. [0]\n"
	"             0x1: Only process reference regions present in/between SAM alignments\n"
	"             0x2: Don't fileter secondary/supplementary SAM records with flag (0x100 | 0x800)\n"
	" -r          Force to use reference mode\n"
	" -p <string> Similar with -d, but translate SAM into wtdbg layout file\n"
	" -i <string> Input file(s) *.ctg.lay from wtdbg, +, [STDIN]\n"
	"             Or sorted SAM files when having -d\n"
	" -o <string> Output files, [STDOUT]\n"
	" -f          Force overwrite\n"
	" -j <int>    Expected max length of node, or say the overlap length of two adjacent units in layout file, [1500] bp\n"

	" -W <int>    Window size in the middle of the first read for fast align remaining reads, [200]\n"
	"             If $W is negative, will disable fast align, but use the abs($W) as Band align score cutoff\n"
	" -w <int>    Min size of aligned size in window, [$W * 0.5]\n"
	"             In sorted-SAM input mode, -w is the sliding window size [2000]\n"
	" -A          Abort TriPOA when any read cannot be fast aligned, then try POA\n"
	" -S <int>    Shuffle mode, 0: don't shuffle reads, 1: by shared kmers, 2: subsampling. [1]\n"
	" -R <int>    Realignment bandwidth, 0: disable, [16]\n"
	" -c <int>    Consensus mode: 0, run-length; 1, dp-call-cns, [0]\n"
