✨ unsplit(1) ✨

okay bestie, so you know how we're deep in the Computational Morphometry Toolkit (aka CMTK, say it with me 👑)? yeah. this is unsplit. it's the manual page. and honestly? it's giving "glue but for images" 💅

🌸 NAME 🌸

unsplit — unsplit images 🫶

like. un-split. it puts the pieces back together. the way that a name can just tell you the whole plot fr fr.

🦋 SYNOPSIS 🦋

unsplit [options] inImage0 inImage1 ...

so you hand it a bunch of images, you can sprinkle in some options if you're feeling fancy, and it does its little magic. no cap. ✨

💖 DESCRIPTION 💖

Join separate image stacks into a single interleaved image volume 🧚

that's it. that's the whole thing. it takes your lil stacks and makes them ONE. main character energy, honestly. one volume to rule them all 💀

🌈 OPTIONS 🌈

💫 Global Toolkit Options (these are shared by all CMTK tools)

okay so these are the every-tool-gets-them options, the group chat regulars, the ones that show up to every party 🎀

  • --help — dumps the list of basic command line options to standard output. your lil starter pack 🌱
  • --help-all — dumps the COMPLETE list of basic AND advanced command line options to standard output. the full lore 📚
  • --wiki — writes the list of command line options to standard output in MediaWiki markup. for when you're documenting, bestie 📝
  • --man — writes man page source in nroff markup to standard output. yes this exact vibe, but unironically 📖
  • --version — writes the toolkit version to standard output. (it's 3.3.1p2, if you were wondering, and we'll get there 💕)
  • --echo — writes the current command line to standard output. it's just repeating you back. mirror moment 🪞
  • --verbose-level <integer> — set the verbosity level. numbers. spice. whatever level you can handle 🔥
  • --verbose, -v — increments the verbosity level by 1. deprecated ngl — it's only still here for backward compatibility, so don't build your whole personality on it 🙈
  • --threads <integer> — sets the maximum number of parallel threads (for POSIX threads and OpenMP). yes queen, parallelize 💅
  • --output <string>, -o <string> — the path for the output image. [Default: NONE] — so if you don't say anything, there's literally no output path, so maybe say something 🫶

🎀 Stacking Options 🎀

this is where the actual stacking happens. the how, the where, the ~axis~ of it all ✨

  • --stacking — define the slice axis for stacking. supported values: "axial", "sagittal", "coronal", "interleave-x", "interleave-y", "interleave-z". the default is "axial". OR, because options within options is iconic, you can use one of these instead:
    • --axial, -a — interleaved axial images. [This is the default] 🔥
    • --sagittal, -s — interleaved sagittal images ✨
    • --coronal, -c — interleaved coronal images ✨
    • --interleave-x, -x — interleaved along the x axis ✨
    • --interleave-y, -y — interleaved along the y axis ✨
    • --interleave-z, -z — interleaved along the z axis. [This is the default] 🔥
  • --spacing <double> — if it's non-zero, this forces the slice spacing in the output image to the value you gave. and listen, this one's important: it is required when you're stacking single-slice images. [Default: 0] 🫶
bestie not me telling you twice — --spacing is literally not optional when your images are single-slice. that's not a vibe, that's a requirement 💀
