Commands

QSMxT is a single binary with a set of subcommands. Run qsmxt <command> --help for the complete, authoritative options of any command.

Pipeline & datasets

Command	Description
run	Run the full QSM pipeline on a BIDS dataset
init	Generate a pipeline configuration file (TOML)
validate	Validate BIDS dataset structure for QSM processing
dicom-convert	Convert a DICOM directory to BIDS with automatic classification
slurm	Generate SLURM job scripts for HPC execution
tui	Launch the interactive TUI
update	Check for and install the latest release

Standalone NIfTI tools

These operate directly on NIfTI files (in/out), independent of the BIDS pipeline. See Standalone tools.

Command	Description
mask	Masking operations (Otsu, value, percentile, BET, morphology)
unwrap	Phase unwrapping
bgremove	Background field removal
invert	Dipole inversion
swi	Susceptibility-weighted imaging
r2star	R2* mapping from multi-echo magnitude
t2star	T2* mapping from multi-echo magnitude
homogeneity	Inhomogeneity correction on magnitude data
resample	Resample an oblique volume to axial orientation
quality-map	Compute a ROMEO phase-quality map
