FASTAQ-TRIM_ENDS(1)

✨ NAME ✨

fastaq_trim_ends — bestie, this one trims a fixed number of bases off the start and/or the end of every sequence. Fix-ed. Number of bases. No cap 💅

---

🌸 DESCRIPTION 🌸

okay so here's the whole vibe:

usage: fastaq_trim_ends <infile> <bases off start> <bases off end> <outfile>

Trim fixed number of bases of start and/or end of every sequence — that's it, that's the girl 🎀

Like literally, you hand it a number for the front, a number for the back, and it does that exact snip to every single sequence in the file. Not one sequence, not a vibe check on some of them — every one 🦋

💖 positional arguments:

• infile — the name of your input file, i.e. where the sequences are currently living 🫶
• start_trim — how many bases get trimmed off the start. that's the front end, the beginning, the opening act ✨
• end_trim — how many bases get trimmed off the end. that's the back end, the closing credits 🌸
• outfile — the name of your output file, i.e. where the trimmed glow-up gets written 💅

👑 options:

• -h, --help — shows this help message and exits. the classic. iconic behaviour, honestly 💖

---

ngl bestie, keep those positionals in order — infile, then start, then end, then outfile — because that's the order the universe (and the argument parser) expects 🙈

and that's the whole page, periodt 💜 this was fastaq_trim_ends version 3.17.0, dated January 2026 — slayed, signed, sealed, no notes 🎀✨💖
