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'.
