++ 3dRankizer: AFNI version=AFNI_2011_12_21_1014 (Dec 16 2015) [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
