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'. ++ Compile date = Mar 28 2024 {AFNI_24.0.18:linux_ubuntu_16_64}
