🌸 LAV2MURASAKI(1) 🌸

okay bestie, so this is part of the User Contributed Perl Documentation, and the star of the show is lav2murasaki.pl. she's a little script with a big job and honestly she ate 💅

---

✨ NAME ✨

lav2murasaki.pl — not me converting a LAV file (like, the ones that come from Blastz) into a whole Murasaki set of files 🦋

like. glow up but for alignment data. periodt.

🎀 SYNOPSIS 🎀

lav2murasaki.pl [options] <input file>

that's it, that's the whole vibe check: you hand her an <input file>, you optionally pass some options, and she goes to work ✨

---

💖 OPTIONS 💖

• --ungapped, -u — okay so here's the tea: LAV files have "gapped regions" that are composed of "ungapped regions". turn this on and she makes 1 anchor for each ungapped region 🫶 (and bonus: this also gives you a .bitscore file, because every ungapped region has a percent identity field in it — iconic, honestly)
• --verbose, -v — more output to stdout, the chattier the merrier 💬 and yes you can stack it up to 3 times. though ngl, anything beyond 1 gets messy, because each anchor gets 1 line of output 😭 like she will simply start yapping. 1 is cute, 3 is a lot, you've been warned bestie.
