Array dimensions must match for binary array op.
显示 更早的评论
I have two groups of images (patients and control subjects) and I am try to perform a two sample t-test but I keep getting this error ''Array dimensions must match for binary array op.'' even though I checked the dimensions of all my images are they are the same (x=46, y=55, and z=46) and their sizes to are the same (voxel size= 3 x 3 x 3). Please I really need help to solve this problem. I am confused as to what array dimensions they are talking about.
Error in y_GroupAnalysis_Image (line 60)
MaskData = any(DependentVolume,4) .* MaskData; % skip the voxels with all zeros

Error in y_GroupAnalysis_Image (line 60)
MaskData = any(DependentVolume,4) .* MaskData; % skip the voxels with all zeros
what is initial value of MaskData?
put a break point on this line and see the size of any(DependentVolume,4) and MaskData

MaskData = any(DependentVolume,4) .* MaskData;
The error message indicates that the problem is in this line. Can you be sure that the result of any(DependentVolume,4) has the same number of elements as MaskData?
