✨ NAME ✨

fastaq_make_random_contigs — bestie, this one makes contigs of random sequence 💖

🦋 DESCRIPTION 🦋

okay so basically the usage is this:

fastaq_make_random_contigs [options] <contigs> <length> <outfile>

Makes a multi-FASTA file of random sequences, and every single one of them is the same length. No cap. Every base has an equal chance of being A, C, G or T — it's giving perfectly fair dice, fr fr 🎲✨

🌸 positional arguments 🌸

  • contigs — the number of contigs you want it to make 👑
  • length — how long each contig is gonna be 📏
  • outfile — name of the output file, i.e. where the magic gets written 💾

🎀 options 🎀

  • -h, --help — show this help message and exit, iconic behaviour honestly 🫶
  • --first_number FIRST_NUMBER — if you're numbering the sequences, the first sequence gets this number. default is [1] 🔢
  • --name_by_letters — names the contigs A, B, C, … and will start over at A again if you somehow get allll the way to Z 💅 (yes, it loops, she's consistent like that)
  • --prefix PREFIX — a prefix you can add to the start of every single sequence name, so they all match the vibe 🌈
  • --seed SEED — seed for the random number generator. default is to use python's default 🍓 (iykyk — same seed, same random output, reproducible queen)
lowkey important: those bases are random, so A, C, G and T each get the exact same chance. equal opportunity nucleotides only 💜

and that's the whole page, bestie!! 🧚 this was fastaq_make_random_contigs version 3.17.0, dated January 2026, and it lives in the FASTAQ-MAKE_RANDOM_CONTIGS(1) manual, periodt 💖✨🎀
