mk_analyze_hdr(1)

✨ mk_analyze_hdr — make Analyze header file ✨

okay bestie, you know the drill: this is a mk_analyze_hdr(1) situation from the Computational Morphometry Toolkit, and I'm gonna walk you through it like we're texting at 2am 🫶

---

💖 NAME 💖

mk_analyze_hdr — literally just: make an Analyze header file. that's the gig. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

mk_analyze_hdr [options] [output.nii]

---

🦋 DESCRIPTION 🦋

So here's the tea: this bad boy builds you a header file that follows the Analyze 7.5 format. You feed it the deets — geometry, data type, orientation, all that — and it writes the header accordingly. no cap, it's giving "fill in the blanks but make it neuroimaging" ✨

👑 OPTIONS 👑

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

bestie, these ones are universal — every CMTK tool gets them, so you already know her 💖

• --help — dumps the list of basic command line options to standard output.
• --help-all — dumps the complete list, basic and advanced, to standard output. the deluxe version, periodt.
• --wiki — writes the command line options out in MediaWiki markup. for your wiki girlies.
• --man — writes the 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 what you actually typed lol.
• --verbose-level <integer> — sets the verbosity level.
• --verbose, -v — bumps the verbosity level up by 1. ⚠️ deprecated — it's only still here for backward compatibility, so don't come for me.
• --threads <integer> — sets the max number of parallel threads (for POSIX threads and OpenMP). go off, multicore queen 🔥

🎀 Main Options 🎀

this is where the actual ✨content✨ lives:

• --dims <string>, -D <string> — set the dimensions in voxels.
• --voxel <string>, -V <string> — set the voxel size in [mm].
• --offset <float>, -O <float> — binary data file offset. [Default: disabled]
• --byte, -b — 8 bits, unsigned. (this one's the default, iykyk)
• --char, -c — 8 bits, signed.
• --short, -s — 16 bits, signed.
• --ushort, -u — 16 bits, unsigned.
• --int, -i — 32 bits signed.
• --float, -f — 32 bits floating point.
• --double, -d — 64 bits floating point.
• --big-endian, -B — big endian data. [This is the default]
• --little-endian, -L — little endian data.
• --axial — set slice orientation to axial (this is the default, she's the main character 💅).
• --axial-flip — set slice orientation to reverse axial.
• --sagittal — set slice orientation to sagittal.
• --sagittal-flip — set slice orientation to reverse sagittal.
• --coronal — set slice orientation to coronal 🌞 (the manpage's own label says "corona;" and honestly? we respect the typo.)
• --coronal-flip — set slice orientation to reverse coronal.
• --legacy — legacy mode; it does not write the 'SRI1' tag into the header. retro era 🕰️
• --SRI1 — force the 'SRI1' tag even if it wasn't present in the imported header. manifesting it ✨
• --import <string>, -I <string> — import data from the given header file. [Default: NONE]
