✨ GT-SKETCH ✨

okay bestie, welcome to gt-sketch, straight outta the GenomeTools Manual 💖 this is the little icon that takes your GFF3 annotation files and turns them into an actual picture — like, a whole graphical representation of them. art. museum. periodt 🎨🦋

🌸 NAME 🌸

gt-sketch — create graphical representation of GFF3 annotation files. yes she draws your genome for you, no cap 💅

🎀 SYNOPSIS 🎀

gt sketch [option ...] image_file [GFF3_file ...]

you give her an image_file (the glow-up destination), and then as many GFF3_files as your heart desires 💖

🦋 DESCRIPTION 🦋

so here's the whole menu of options, babes. every single one. i'm not gatekeeping a thing, iykyk 🌈

  • -pipe [yes|no] — turns on pipe mode, which means all the gff3 features get shown on stdout instead of going into an image. default: no 🫶
  • -flattenfiles [yes|no] — does not group your tracks by source file name, and it also strips the file names out of the track description. default: no ✨
  • -seqid [string] — the sequence region identifier you wanna look at. default: the first one in the file 🧚
  • -start [value] — the start position. default: the first region start 🌸
  • -end [value] — the end position. default: the last region end 💜
  • -width [value] — your target image width, in pixels. default: 800 (yes that's the vibe check number) 📏
  • -style [string] — the style file to use. default: undefined — so if you don't hand her one, there isn't one 👑
  • -format [...] — output graphics format, choose from png|pdf|svg|ps. default: png 🖼️
  • -input [...] — input data format, choose from gff|bed|gtf. default: gff 📥
  • -addintrons [yes|no] — adds intron features between the existing exon features (and she does it before drawing, so it actually shows up). default: no 🧬
  • -unsafe [yes|no] — enables unsafe mode for the style file. default: no 😭 (it's literally called unsafe, so like… know that before you flip it, bestie)
  • -v [yes|no] — be verbose. default: no 🗣️
  • -force [yes|no] — force writing to the output file. default: no 💪
  • -help — display help and exit 🙋‍♀️
  • -version — display version information and exit 🏷️

💀 REPORTING BUGS 💀

found a bug? not the vibe, but okay, report it here:

https://github.com/genometools/genometools/issues

she'll get it fixed, we don't do silent suffering in this group chat 🙈🫶

quick reminder bestie: that -unsafe flag is called unsafe for a reason — it's unsafe mode for the style file. read the room before you enable it 💅
