+Usage:   seqtk seq [options] <in.fq>|<in.fa>
+
+Options: -q INT    mask bases with quality lower than INT [0]
+         -n CHAR   masked bases converted to CHAR; 0 for lowercase [0]
+         -l INT    number of residues per line; 0 for 2^32-1 [0]
+         -Q INT    quality shift: ASCII-INT gives base quality [33]
+         -s INT    random seed (effective with -f) [11]
+         -f FLOAT  sample FLOAT fraction of sequences [1]
+         -M FILE   mask regions in BED or name list FILE [null]
+         -L INT    drop sequences with length shorter than INT [0]
+         -c        mask complement region (effective with -M)
+         -r        reverse complement
+         -A        force FASTA output (discard quality)
+         -C        drop comments at the header lines
