minc_rank

Convert voxel intensities to rank values in the range 0-100.

minc_rank [options] <source> <output>

DESCRIPTION

minc_rank converts voxel intensities in a MINC volume into rank-based percentile values ranging from 0 to 100. Each voxel’s output value represents its percentile position in the overall intensity distribution. This is useful for normalizing intensity distributions across subjects or for non-parametric statistical analyses.

OPTIONS

--mask mask.mnc

Restrict the rank computation to voxels within the specified binary mask. Voxels outside the mask will have a value of 0 in the output.

--fix_zero_padding

Handle zero-padded regions by excluding them from the ranking.

--verbose

Print progress information during processing.

EXAMPLES

Convert intensities to ranks:

minc_rank source.mnc ranked.mnc

Convert intensities to ranks within a brain mask:

minc_rank --mask brainmask.mnc source.mnc ranked.mnc
