UNU-AXMERGE(1)

💖 UNU-AXMERGE(1) 💖

okay bestie, so this is the manual for unu-axmerge, a lil User Command that lives in the unu family, and honestly? it's giving axis glow-up. 🦋

---

✨ NAME ✨

unu-axmerge — merge two adjacent axes into one 🔥

---

🌸 SYNOPSIS 🌸

unu axmerge -a,--axis <ax0 ...> [-i,--input <nin>] [-o,--output <nout>]

---

💅 DESCRIPTION 💅

So basically, unu-axmerge takes two adjacent axes and smushes them into one single axis. no cap. 🫶

Think of it as the more general, more main-character version of unu-axdelete(1) — like axdelete but with ✨range✨.

Here's the tea tho: the underlying linear ordering of the samples is not changed. like, at all. not even a little. What does move is the info about the other axes — that gets shifted downwards as needed to make room. 🎀

• Uses nrrdAxesMerge

---

👑 OPTIONS 👑

• -a <ax0 ...> , --axis <ax0 ...> — the axis (or axes, plural, we love a group project) that you're merging. every axis index you name here is the lower one of the pair that's getting merged, iykyk. so saying -a 2 means merge axis 2 and axis 3 into axis 2. and if you're doing multiple merges at once? the indices you list are for the axes prior to any merging — like, before any of the merging happens, so don't be out here renumbering in your head, bestie. 😭 (1 or more ints)
• -i <nin> , --input <nin> — the input nrrd 📥
• -o <nout> , --output <nout> — the output nrrd (string); default: "-" 📤

mwah 💋 this was the unu-axmerge page from August 2021, part of the User Commands collection — that's the source/version and date, bestie, and yes I remembered them. periodt. ⭐
