GT-SEQFILTER(1)

✨ NAME ✨

gt-seqfilter — filter the given sequence file(s) and show the results on stdout. That's the whole point, bestie. This is the GT-SEQFILTER(1) manual page from the GenomeTools Manual, and it's giving "sequence filter, but make it cute." 💖

🦋 SYNOPSIS 🦋

gt seqfilter [option ...] [sequence_file ...]

That's the shape of it: options first, sequence files after, and then it does its thing on stdout. No cap.

💅 DESCRIPTION 💅

okay so the tea is that all the filtering behavior lives in these options. Every single one, fr fr. Defaults are in parentheses, periodt. ✨

• -minlength [value] — set minimum length a sequence must have to pass the filter (default: undefined)
• -maxlength [value] — set maximum length a sequence can have to pass the filter (default: undefined)
• -maxseqnum [value] — set the maximum number of sequences which can pass the filter (default: undefined)
• -sample [value] — set a probability for each sequence to pass the filter (default: 1.000000)
• -step [value] — only every step-th sequence passes the filter (default: 1)
• -nowildcards [yes|no] — filter out seqences containing wildcards (default: no)
• -width [value] — set output width for FASTA sequence printing (0 disables formatting) (default: 0)
• -o [filename] — redirect output to specified file (default: undefined)
• -gzip [yes|no] — write gzip compressed output file (default: no)
• -bzip2 [yes|no] — write bzip2 compressed output file (default: no)
• -force [yes|no] — force writing to output file (default: no)
• -help — display help and exit
• -version — display version information and exit

so yeah, mix and match those flags and your sequences are gonna get filtered, bestie. it's iconic. 💅
