++ 3dMannWhitney: AFNI version=AFNI_2011_12_21_1014 (Dec 16 2015) [64-bit] ++ Authored by: B. Douglas Ward This program performs nonparametric Mann-Whitney two-sample test.

Usage: 3dMannWhitney

-dset 1 filename data set for X observations
. . . . . .

-dset 1 filename data set for X observations -dset 2 filename data set for Y observations

. . . . . .

-dset 2 filename data set for Y observations

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

[-voxel num] screen output for voxel # num

-out prefixname estimated population delta and
Wilcoxon-Mann-Whitney statistics 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’.
