AFNI program: 3dRankizer
Output of -help
++ 3dRankizer: AFNI version=AFNI_24.3.06 (Oct 31 2024) [64-bit]
++ Authored by: Zhark of the Ineffable Rank
Usage: 3dRankizer [options] dataset
Output = Rank of each voxel as sorted into increasing value.
- Ties get the average rank.
- Not the same as 3dRank!
- Only sub-brick #0 is processed at this time!
- Ranks start at 1 and increase:
Input = 0 3 4 4 7 9
Output = 1 2 3.5 3.5 5 6
Options:
-brank bbb Set the 'base' rank to 'bbb' instead of 1.
(You could also do this with 3dcalc.)
-mask mset Means to use the dataset 'mset' as a mask:
Only voxels with nonzero values in 'mset'
will be used from 'dataset'. Voxels outside
the mask will get rank 0.
-prefix ppp Write results into float-format dataset 'ppp'
Output is in float format to allow for
non-integer ranks resulting from ties.
-percentize : Divide rank by the number of voxels in the dataset x 100.0
-percentize_mask : Divide rank by the number of voxels in the mask x 100.0
