💖 FASTAQ-ACGTN_ONLY(1) 💖

okay bestie, we're in the User Commands corner of the manual and this little cutie is called fastaq_acgtn_only. she's giving cleanup-crew energy and honestly? iconic. 🧹✨

🌸 NAME 🌸

fastaq_acgtn_only — replaces every single character that isn't an acgtnACGTN with an N. that's it. that's the whole job. no cap. 💅

🦋 DESCRIPTION 🦋

so here's the vibe check. you run her like this:

fastaq_acgtn_only [options] <infile> <outfile>

and what she does is literally this: any character that is not one of acgtACGTnN gets swapped out for an N. every. single. one. she does not care what it was, she does not ask questions, it becomes an N. periodt. 🔥

🎀 positional arguments

these are the two besties she needs to actually do anything:

  • infile — the name of the input file. the one she reads from. 📥
  • outfile — the name of the output file. the one she writes to. 📤

✨ options

  • -h, --help — shows this help message and then exits. classic. she's helpful like that. 🫶
⚠️ heads up bestie: she's strict about what counts as "allowed". if it's not an a, c, g, t, A, C, G, T, n, or N, it is getting turned into an N. no exceptions, no mercy, no thoughts. 💀

and that's the whole page, my love. 🌈 this was fastaq_acgtn_only version 3.17.0, dated January 2026 — so fresh, so shiny, so acgtn-only. go forth and sanitise those sequences. i'm obsessed. 💜🎀🦋
