UNU-HISTO(1)

💖 unu-histo(1) — bestie edition 💖

okay so you found the unu-histo page in section 1 of the manual, and honestly? it's giving histogram queen 👑 this is a user command, and it's about to make your nrrd data make sense.

✨ NAME ✨

unu-histo — create a 1-D histogram of values in a nrrd. no cap, that's the whole job 🎀

🌸 SYNOPSIS 🌸

unu histo -b,--bins <num> [-w,--weight <nweight>] [-min,--minimum
<value>] [-max,--maximum <value>] [-blind8 <bool>] [-t,--type <type>]
[-i,--input <nin>] [-o,--output <nout>]

🦋 DESCRIPTION 🦋

So basically: this makes a 1-D histogram of the values chillin' in a nrrd 💅 You can either spell out the bounds of the histogram domain yourself, or you can just let it learn them from the data like the independent little icon it is ✨

• Uses nrrdHisto 💖

🎀 OPTIONS 🎀

• -b <num>, --bins <num> — how many bins are in the histogram (unsigned int). this one's required btw, it's the whole vibe 🔥
• -w <nweight>, --weight <nweight> — how to weigh contributions to the histogram. by default (aka if you don't use this option), the increment is one bin count per sample 🍓 but if you hand it a nrrd, then the value in that nrrd at the corresponding location becomes the bin count increment. fancy, right? ✨
• -min <value>, --minimum <value> — the value at the low end of the histogram. you can give it as a regular number, or — plot twist — if you tack a % suffix on that number, this minimum is specified in terms of the percentage of samples in the input that are lower 🙈 by default (not using this option), it's the lowest value found in the input nrrd. (string); default: "nan"
• -max <value>, --maximum <value> — the value at the high end of the histogram. same deal as min: regular number, or with a % suffix it means the percentage of samples in the input that are higher 💜 defaults to the highest value found in the input nrrd. (string); default: "nan"
• -blind8 <bool> — whether to know the range of 8-bit data blindly, like it's just born knowing (uchar is always [0,255], signed char is [-128,127]). (bool); default: "true" 👑
• -t <type>, --type <type> — the type to use for the bins in the output histogram; default: "uint" ⭐
• -i <nin>, --input <nin> — the input nrrd 🌸
• -o <nout>, --output <nout> — the output nrrd (string); default: "-" 💫
