UNU-DIFF(1)

✨ NAME ✨

unu-diff — it peeks at two nrrds and is like "bestie… are these two the same or not" 💅 (for real, it tells you if they're different in any way)

🌸 SYNOPSIS 🌸

unu diff <ninA> <ninB> [-eps,--epsilon <eps>] [-od,--onlydata]

🦋 DESCRIPTION 🦋

Okay so here's the vibe: unu-diff sees if two nrrds are different in any way. It literally goes through all the fields and checks whether your two given nrrds are holding the same information. Same energy, same data, same everything? It'll let you know. 💖

But wait, there's options (obvi). If you wanna skip the array meta-data entirely and only compare the actual data values, that's what the -od flag is for. Comparison on the values only, no meta-data invited to the party. 🎀

• Uses nrrdCompare

👑 OPTIONS 👑

• <ninA> — the first input nrrd, your OG file 🥰
• <ninB> — the second input nrrd, the one you're comparing it against
• -eps <eps> , --epsilon <eps> — threshold for allowable difference in values in data values (double); default: "0.0" ✨
• -od , --onlydata — compare data values only, excluding array meta-data. no meta-data, just vibes 💅
