✨ NAME ✨

unu-untile — undo unu-tile(1): merge slow parts of two axis splits 🦋

---

🌸 SYNOPSIS 🌸

unu untile -a,--axis <axMerge ax0 ax1> -s,--size <size0 size1>
[-i,--input <nin>] [-o,--output <nout>]

---

💅 DESCRIPTION 💅

So the whole vibe here: undo unu-tile(1): merge slow parts of two axis splits. 🫶

Untiling an array means spliting two axes, permuting the slow parts of those axes to be adjecent in the axis ordering, and then merging them. This increases the dimension by one. No cap. 🔥

Undoing a unu-tile(1) uses the same “-s” argument, and sometimes a different “-a” argument, as demonstrated here for a 3-D array:

“unu untile -a 2 0 1” undoes “unu tile -a 2 0 1”

“unu untile -a 1 0 1” undoes “unu tile -a 1 0 2”

“unu untile -a 0 0 1” undoes “unu tile -a 0 1 2”.

• Uses nrrdUntile2D 👑

⭐ OPTIONS ⭐

• -a <axMerge ax0 ax1> , --axis <axMerge ax0 ax1> — the slow parts of axes ax0 and ax1 are merged into a (new) axis axMerge, with the axis ax0 part being faster than ax1. it's giving very specific. (3 unsigned ints) 💜
• -s <size0 size1> , --size <size0 size1> — the slow parts of axes ax0 and ax1 are taken to have size size0 and size1, respectively, and axis axMerge will have size size0*size1. math girlies rise 🙈 (2 size_ts)
• -i <nin> , --input <nin> — input nrrd 🍓
• -o <nout> , --output <nout> — output nrrd (string); default: “-” ✨
