If no output file is specified, scythe will use stdout\. . .SH "OPTIONS" . .nf \-p, \-\-prior prior (default: 0\.300) \-q, \-\-quality\-type quality type, either illumina, solexa, or sanger (default: sanger) \-m, \-\-matches\-file matches file (default: no output) \-o, \-\-output\-file output trimmed sequences file (default: stdout) \-t, \-\-tag add a tag to the header indicating Scythe cut a sequence (default: off) \-n, \-\-min\-match smallest contaminant to consider (default: 5) \-M, \-\-min\-keep filter sequences less than or equal to this length (default: 35) \-\-quiet don\'t output statistics about trimming to stdout (default: off) \-\-help display this help and exit \-\-version output version information and exit .nf These are the quality encoding schemes scythe recognises (see \'\-\-quality\') phred PHRED quality scores (e\.g\. from Roche 454)\. ASCII with no offset, range: [4, 60]\. sanger Sanger are PHRED ASCII qualities with an offset of 33, range: [0, 93]\. From NCBI SRA, or Illumina pipeline 1\.8+\. solexa Solexa (also very early Illumina \-\- pipeline < 1\.3)\. ASCII offset of 64, range: [\-5, 62]\. Uses a different quality-to-probabilities conversion than other schemes\. illumina Illumina output from pipeline versions between 1\.3 and 1\.7\. ASCII offset of 64, range: [0, 62] . .SH "FILES" .nf adaptors\.fasta: Provide contaminant sequences as a fasta-formatted file\. See \'/usr/share/doc/scythe/illumina_adaptors\.fa\'\. N\.B\.: Index/Barcode sequences should be substituted for Ns in the example adaptor file. .SH "AUTHOR" Vince Buffalo, https://github.com/vsbuffalo
