💖 fit_spline_dfield(1) 💖

okay bestie, welcome to the Computational Morphology Toolkit — CMTK for the girlies who are deep in the neuroimaging trenches 💅. this is the man page for fit_spline_dfield, and we are gonna get you fluent.

✨ NAME ✨

fit_spline_dfield — Deformation Field to Transformation 🦋

✨ SYNOPSIS ✨

fit_spline_dfield InputDField OutputXform

✨ DESCRIPTION ✨

so basically 🌸: it fits a parametric nonrigid transformation — specifically a B-spline free-form deformation — to a deformation field. that's it. that's the whole job. she takes your field and she gives you a parametric glow-up. iconic.

✨ OPTIONS ✨

🌈 Global Toolkit Options (these are shared by all CMTK tools)

like, these ones are the communal wardrobe. every CMTK tool wears them 🫶

  • --help — writes the list of basic command line options to standard output. the "hey what do i do" button ✨
  • --help-all — writes the complete list of basic and advanced command line options to standard output. the deluxe, no-holds-barred version 👑
  • --wiki — writes the list of command line options to standard output in MediaWiki markup. wiki girlies, this one's for you 📝
  • --man — writes man page source in 'nroff' markup to standard output. meta. very meta.
  • --version — writes toolkit version to standard output. who am i, what year is it 🎀
  • --echo — writes the current command line to standard output. so you can see exactly what you just did 😭
  • --verbose-level <integer> — set verbosity level. dial the yapping up or down.
  • --verbose, -v — increment verbosity level by 1 (deprecated; supported for backward compatibility). okay so she's deprecated but she's still showing up, and honestly? respect 🫡
  • --threads <integer> — set maximum number of parallel threads (for POSIX threads and OpenMP). multitasking queen 🔥

🎀 Input Options

  • --absolute — input is an absolute transformation field [x maps to input(x)]. [This is the default] — so if you don't say anything, this is what you get 💖
  • --relative — input is a relative deformation field, e.g., a gradient or force field [x maps to x+input(x)]. noting the difference, because it literally matters ✨

🧚 Fitting Options

  • --levels <integer> — Number of levels in the multi-level B-spline approximation procedure. [Default: 1]
  • --fit-affine-first — Fit affine transformation first, then initialize spline with it. affine first, spline second, main character energy both times 👑

🍓 Output Options

  • --final-cp-spacing <double> — Final control point grid spacing of the output B-spline transformation. [Default: 0]
  • --final-cp-dims <string> — Final control point grid dimensions (i.e., number of controlpoints) of the output B-spline transformation. To be provided as 'dimX,dimY,dimZ'. [Default: NONE]

and that's the whole page, babe 🦋 this was CMTK 3.3.1p2, dated Jun 24 2026 — so yes, future-proof, still slaying, still fitting those splines. go forth and be iconic 💅✨
