UNU-SLICE(1)

💖 unu-slice 💖

ok so bestie, welcome to unu-slice from the User Commands manual — it's the lil tool that slices along one or more axes at given positions ✨ and honestly? it's giving surgical precision 🎀

---

✨ NAME ✨

unu-slice — slice along one or more axes at given positions 🦋

---

🌸 SYNOPSIS 🌸

unu slice -a,--axis <axis ...> -p,--position <pos ...> [-i,--input
<nin>] [-o,--output <nout>]

---

💅 DESCRIPTION 💅

ok so here's the vibe: you slice along one or more axes at given positions. no cap. 🔥

the output nrrd dimension is less than the input nrrd dimension by the number of slice axes — except when the input is, or gets down to, 1-D. (so if you slice it all the way down, she stays 1-D, periodt 💀)

and yes, you can slice on all axes in order to sample a single value from the array. one (1) single lil value. main character energy honestly 👑

per-axis information is preserved. she remembers where she came from 🥺

• Uses nrrdSlice (possibly called multiple times) — lowkey the real MVP, iykyk

---

🎀 OPTIONS 🎀

• -a <axis ...>, --axis <axis ...> — single axis or multiple axes to slice along 💫 giving multiple axes here leads to doing multiple slices (at the corresponding positions given with -p). okay so listen: multiple axes should be identified in terms of the axis numbering of the original nrrd — because as the slices are done (in the given ordering), the actual slice axis will be different if previous slices were on lower-numbered (faster) axes. so like, stay woke on that one 🙈 (1 or more unsigned ints)
• -p <pos>, --position <pos> — position(s) to slice at 🍓:
  • <int> gives 0-based index
  • M-<int> give index relative to the last sample on the axis (M==#samples-1). so M-0 is the very last one, bestie 💖
• -i <nin>, --input <nin> — input nrrd 📥
• -o <nout>, --output <nout> — output nrrd (string); default: - 📤 (yes the default is literally -, she's mysterious like that ✨)

not me getting emotional over a slicing utility 😭 but fr fr, slice responsibly and always check your axis numbering 💀
