💖 edfcat(1) — the EDF channel mixer/converter, bestie edition 💖

okay so you found edfcat, the little cutie from the Aghermann family that rearranges EDF file channels for you. she's a channel mixer/converter, she's lowkey iconic, and she's about to become your fave. 🦋

✨ NAME ✨

edfcat — EDF file channel mixer/converter. that's it, that's the girl. 💅

✨ SYNOPSIS ✨

edfcat OPERATION OPERANDS

like, operation first, operands after. main character energy from the very first token. 👑

✨ DESCRIPTION ✨

edfcat is a tool to manipulate EDF file channels. fr fr, that's her whole job.

Currently, two operations are supported:

  1. ascii->edf conversion — but ngl, the multichannel conversion is restricted to channels with identical samplerate. if your sample rates are mismatched, that's not it, bestie. 😭
  2. channel pruning — she keeps the channels you want and drops the rest. slay. ✂️

🌸 the operations, one by one 🌸

  • conv FILE.ascii SAMPLERATE RECORD_SIZE — Convert samples in FILE.ascii into FILE.ascii.edf. Multiple columns in the source file will be converted as individual channels. 🎀

On success, physical_min/physical_max in each channel will be set to the absolute min/max of all channel data, widened symmetrically to whichever boundary is farther from 0. So a range of -2:3 becomes -3:3, as will -3:2. symmetry queen behavior. ⚖️✨

  • prune FILE.edf N1[,N2,...] — Create a copy of the source file (FILE-mod.edf) only keeping channels N1,N2,..., and yes those are 1-based. don't come at me with 0-indexing, that's just what the page says. 🙈
heads up: conv only plays nice when every channel has the same samplerate. mismatched rates = no conversion for you. 💀
