💖 extract_ascii(1) 💖

okay bestie, welcome to the user commands section, we're doing extract_ascii today and honestly? it's giving scientific data pipeline and I'm obsessed 🦋

✨ NAME ✨

extract_ascii — the manual page for extract_ascii version 2026.2, no cap 💅

🌸 DESCRIPTION 🌸

so first thing you see when you run this is a whole warning situation, and like, it's not your fault, it's just the library being dramatic. here's exactly what it says:

/usr/lib/python3/dist-packages/pytools/persistent_dict.py:52:
RecommendedHashNotFoundWarning: Unable to import recommended hash
'siphash24.siphash13', falling back to 'hashlib.sha256'. Run 'python3 -m
pip install siphash24' to install the recommended hash.

and then it goes:

warn("Unable to import recommended hash 'siphash24.siphash13', "

like okayyy we get it, no siphash24.siphash13 today, hashlib.sha256 is carrying the team, it's fine, we move 🫶

here's the usage line, screenshot it, memorize it:

usage: extract-ascii.py [OPTIONS] FILES

what does it actually do tho? it extracts the SAXS data from a Nexus file and hands it back to you as a 3 column ascii — that's q, I, err in that order, periodt. and the metadata? those get exported in the headers as needed. slay ✨

🎀 positional arguments 🎀

  • FILE — your HDF5 input data, aka the snack you're feeding it 💖

👑 options 👑

  • -h, --help — shows this help message and dips. iconic behaviour honestly
  • -v, --verbose — switches to verbose mode, so it tells you everything it's doing. main character energy 🔥
  • -V, --version — shows the program's version number and exits. quick lil flex 💅
  • -a, --all — extracts every individual frame, not just the one. go big or go home 🌈
  • -z, --zip — extracts every individual frame into a zip-file. so organized, so cute 🎀

and one more thing bestie: extract_ascii.py lets you export the data in inverse nm or inverse A, with possible intensity scaling. yes, units AND scaling, we love options 💜
