regress(1)

🦋 regress(1) 🦋

hey bestie 💖 welcome to regress, one of the tools in The Computational Morphology Toolkit (CMTK, for the girlies who do medical imaging ✨). she does linear — and higher-order polynomial — regression of deformation fields and images. no cap. let's get into it 👑

---

✨ SYNOPSIS ✨

regress [options] controlFile

---

🌸 DESCRIPTION 🌸

k so basically: linear (and higher-order polynomial) regression of deformation fields and images. that's the whole vibe. you hand her a controlFile, she regresses. slay 💅

---

🎀 OPTIONS 🎀

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

these are the universal ones, the ones every CMTK tool has in common, the girlies of the group chat 💅

• --help — writes the list of basic command line options to standard output.
• --help-all — writes the complete list of basic and advanced command line options to standard output. she's thorough.
• --wiki — writes the list of command line options to standard output in MediaWiki markup. for your wiki era 🫶
• --man — writes man page source in 'nroff' markup to standard output. manpage-ception 🤯
• --version — writes the toolkit version to standard output.
• --echo — writes the current command line to standard output. so you can see exactly what you just did, iconic.
• --verbose-level <integer> — sets the verbosity level. pick a number, any number.
• --verbose, -v — increments the verbosity level by 1. deprecated bestie — it only hangs around for backward compatibility 😭 use --verbose-level instead, fr fr.
• --threads <integer> — sets the maximum number of parallel threads (for POSIX threads and OpenMP). more threads, more chaos, more speed 🔥

🌈 Main Options

the actual main-character options, this is where the plot happens 👑

• --output <string>, -o <string> — file name for output. [Default: NONE] (yeah, none — you gotta ask for it 🌸)
• --parameters <string>, -p <string> — model parameters for regression instantiation. [Default: NONE]
• --substitution <string>, -s <string> — printf format string for ID-to-path substitition. [Default: %s ] — and yes, the man page really spells it "substitition" and yes there really is a space in there before that bracket, we do not make the rules 😭💀
• --order <integer>, -O <integer> — polynomial order of the regression. the man page says "Polynonial", which is a typo and honestly kind of a serve 💅 [default: 1=linear] [Default: 1]
