++ 3dKruskalWallis: AFNI version=AFNI_2011_12_21_1014 (Dec 16 2015) [64-bit] ++ Authored by: B. Douglas Ward This program performs nonparametric Kruskal-Wallis test for comparison of multiple treatments.

Usage: 3dKruskalWallis

-levels s s = number of treatments

-dset 1 filename data set for treatment #1
. . . . . .
-dset 1 filename data set for treatment #1
. . . . . .
-dset s filename data set for treatment #s
. . . . . .

-dset s filename data set for treatment #s

[-workmem mega] number of megabytes of RAM to use
for statistical workspace

[-voxel num] screen output for voxel # num

-out prefixnamename Kruskal-Wallis statistics are written
to file prefixname
N.B.: For this program, the user must specify 1 and only 1 sub-brick
with each -dset command. That is, if an input dataset contains more than 1 sub-brick, a sub-brick selector must be used, e.g.: -dset 2 ‘fred+orig[3]’

INPUT DATASET NAMES

This program accepts datasets that are modified on input according to the following schemes:

‘r1+orig[3..5]’ {sub-brick selector} ‘r1+orig<100..200>’ {sub-range selector} ‘r1+orig[3..5]<100..200>’ {both selectors} ‘3dcalc( -a r1+orig -b r2+orig -expr 0.5*(a+b) )’ {calculation}

For the gruesome details, see the output of ‘afni -help’.
