💖 USAGE:(1) 💖

okay bestie, so this is a page from the User Commands section of the manual, and it's literally the whole lore of usage: — the manpage for usage: tff_simple_compare [-h] [--reference REFERENCE]. yes the command name is that long. she's extra. we respect it. 👑

---

✨ NAME ✨

usage: — manual page for usage: tff_simple_compare [-h] [--reference REFERENCE]

---

🌸 DESCRIPTION 🌸

okay so here's the whole vibe, no cap:

usage: tff_simple_compare [-h] [--reference REFERENCE]

       IN_TRACTOGRAM IN_TRACTOGRAM

She does a simple comparison of tractogram by subtracting the coordinates' data. That's the whole job. 🫶

⚠️ heads up: she does not account for shuffling of streamlines. So if your streamlines got rearranged, she is not gonna notice. Simple A-B operations only, periodt.

And now the numbers, because these matter and I'm not gatekeeping:

• Differences below 1e^3 are expected for affine with large rotation/scaling. 💀
• Difference below 1e^6 are expected for isotropic data with small rotation. ✨

---

🎀 positional arguments:

• IN_TRACTOGRAM — Tractogram filename. Format must be one of trk, tck, vtk, fib, dpy, trx. that's the list, she's picky and that's her right 💅

---

🌈 options:

• -h, --help — show this help message and exit. the classic. the icon. she ate. 🍓
• --reference REFERENCE — Reference anatomy for tck/vtk/fib/dpy file support (.nii or .nii.gz).

IN_TRACTOGRAM IN_TRACTOGRAM

💀 the error you will absolutely meet

tff_simple_compare: error: the following arguments are required: IN_TRACTOGRAM

yeah. if you forget to hand her a tractogram she WILL let you know. not me getting this error on the first try 🙈

and that's the page, bestie — go compare some tractograms, you got this. mwah. 🧚💜
