FASTAQ-DEINTERLEAVE(1)

💖 fastaq_deinterleave — the vibe is SPLITTING, bestie 💖

okay so real quick, this is fastaq_deinterleave(1) from the User Commands crew, and she is here to take one interleaved paired file and turn it into two separate ones. no cap. two whole files. let's go 🦋

✨ NAME ✨

fastaq_deinterleave — Splits interleaved paired file into two separate files 🎀

---

🌸 DESCRIPTION 🌸

the usage line, iconic as always:

fastaq_deinterleave [options] <infile> <out_fwd> <out_rev>

so what she actually does: she deinterleaves the sequence file, meaning the reads get written alternately between the two output files. one for you, one for you, one for you, one for you — take turns, besties 💅

🫶 positional arguments 🫶

• infile — Name of fasta/q file to be deinterleaved. this is the one getting taken apart, be gentle with her 💖
• out_fwd — Name of output fasta/q file of forwards reads. the forward girlies go here ✨
• out_rev — Name of output fasta/q file of reverse reads. and the reverse girlies go here 🌈

💅 options 💅

• -h, --help — show this help message and exit. the classic. when in doubt, ask her 🥰
• --fasta_out — Use this to write output as fasta. note that the default is the same as input, so if you don't pass this, she matches whatever you fed her 🎀

---

💀 reminder bestie: the default output format is literally just "same as input". don't be surprised when she copies the vibe she was given. periodt.

so that's the whole page, she's short and she's perfect, we love a low-maintenance icon 👑
