✨ NAME ✨

unu-permute — permute ordering of axes

like, you're shuffling which axis goes where. a glow-up for your dimensions. 🔥

---

🌸 SYNOPSIS 🌸

unu permute -p,--permute <ax0 ax1 ...> [-i,--input <nin>] [-o,--output <nout>]

---

🦋 DESCRIPTION 🦋

So. Permute ordering of axes. 💫 The permutation gives the new ordering of the old axes (in 0-based numbering — yes bestie, we start counting at 0, we're not animals).

For example, the permutation 0->1, 1->2, 2->0 would be 2 0 1.

no cap, read that twice if you need to. 0 goes to 1, 1 goes to 2, 2 goes to 0, and the way you say that is 2 0 1. iconic behavior.

👑 OPTIONS 👑

• -p <ax0 ax1 ...> , --permute <ax0 ax1 ...> — new axis ordering (1 or more unsigned ints). yes literally just one is allowed, the page says "1 or more", and we respect the page 💖
• -i <nin> , --input <nin> — input nrrd. your lil data bestie going in 🎀
• -o <nout> , --output <nout> — output nrrd (string); default: “-”. that default - means it goes to stdout, so it can just spill out into your terminal like a main character ✨
