okay bestie, listen up — this is unu-ccadj, a lil member of the User Commands squad, and she is so good at what she does. no cap.

✨ NAME ✨

unu-ccadj — form adjacency matrix of connected components 🫶

🌸 SYNOPSIS 🌸

unu ccadj -c,--connect <connectivity> [-i,--input <nin>] [-o,--output
<nout>]

🦋 DESCRIPTION 🦋

So the whole vibe here is: we're forming an adjacency matrix of connected components. And no, she doesn't work on just anything — this operates on the output of unu-ccfind(1), so make sure you've run that first or it's giving confused energy. 🙈

The output? An unsigned char array with a 1 sitting at locations (I,J) and (J,I) whenever the CCs with ids I and J are adjacent — and which CCs count as adjacent depends on the style of adjacency you picked. you get to choose, main character behaviour honestly 💅

• Uses nrrdCCAdjacency

💅 OPTIONS 💅

• -c <connectivity>, --connect <connectivity> — picks what kind of connectivity we're using, aka the number of coordinates that vary in order to traverse the neighborhood of a given sample. In 2D: "1" means 4-connected, "2" means 8-connected. Type is unsigned int. ⭐
• -o <nout>, --output <nout> — the output nrrd (string). default: "-" 🎀
