Dear all,
Right now I have two groups of subjects' data, and I am going to apply t test onto them.
the script i am using is as follows:
3dttest++\
-prefix GroupAvsGroupB\
-setA \
sub1_GLM+tlrc[1] \
sub2_GLM+tlrc[1] \
.
.
.
sub20_GLM+tlrc[1] \
-setB \
sub21_GLM+tlrc[1] \
sub22_GLM+tlrc[1] \
.
.
.
sub30_GLM+tlrc[1]
And a
error message showed up:
"FATAL ERROR: -setA and -setB datasets don't match number of voxels"
I would be much thankful if someone could tell me how to handle this.
Best,
Zhizhou
