USAGE:(1)

🎀 NAME 🎀

okay so bestie, this is the manual page for usage:, aka the manpage for usage: tff_concatenate_tractograms [-h] [--delete_dpv] [--delete_dps] — yes the name literally contains the whole usage line, she's extra like that 💅

---

✨ DESCRIPTION ✨

here's the whole vibe, verbatim, because I refuse to paraphrase a synopsis:

usage: tff_concatenate_tractograms [-h] [--delete_dpv] [--delete_dps]
       [--delete_groups] [--reference REFERENCE]
       [-f] in_tractograms [in_tractograms ...]  out_tractogram

so what does she DO? Concatenate multiple tractograms into one. that's it, that's the whole job, and she ate 🔥

but here's the tea, and it's important tea: if the data_per_point or data_per_streamline is not the same for all tractograms, then the data must be deleted first. no cap. you can't just mash them together and hope, bestie 😭

---

🌸 positional arguments: 🌸

• in_tractograms — a tractogram filename, and the format has to be one of trk, tck, vtk, fib, dpy, trx. you can pass a whole lil squad of them, that's what the [in_tractograms ...] is doing 🫶
• out_tractogram — the filename of the concatenated tractogram, aka where the merged masterpiece gets written 💖

---

👑 options: 👑

• -h, --help — show this help message and exit. the classic. the icon. the "wait what does this do again" button ✨
• --delete_dpv — delete the dpv if it exists. Required if not all input has the same metadata. (she's not being dramatic, she means it 🙈)
• --delete_dps — delete the dps if it exists. Required if not all input has the same metadata.
• --delete_groups — delete the groups if it exists. Required if not all input has the same metadata.
• --reference REFERENCE — reference anatomy for tck/vtk/fib/dpy file support (.nii or .nii.gz). yes the extension goes in there, don't forget it 💅
• -f — force overwriting of the output files. be careful, she will absolutely overwrite your stuff ⚠️

and then, because the original page is a little chaotic (respectfully), it just... says this again:

       [--delete_groups] [--reference REFERENCE]
              [-f] in_tractograms [in_tractograms ...]  out_tractogram

same synopsis, bestie, we move 💀

---

😭 the part where she yells at you 😭

if you forget the required stuff, you get exactly this:

tff_concatenate_tractograms: error: the following arguments are required: in_tractograms, out_tractogram

which is giving "not me forgetting the two most important arguments" energy. give her in_tractograms and out_tractogram and she's happy 🌈

---

and that's the whole page, bestie 🦋 this was the USAGE:(1) manual page, from September 2025, and the source line is usage: tff_concatenate_tracto... (yes it's truncated with dots, that's literally how it's printed, iykyk 💜). go concatenate something, you've got this 🫶✨
