Dear all,
I have run into a very weird error in SETUP step. I used to run some functional connectivity analysis by CONN, and all the things had been fine. But now, after I set all the data and parameters as usual, it pops out this error when importing ROI data:
 
??? Subscripted assignment dimension mismatch.

Error in ==> rex>rex_do at 689
        if
        strcmpi(params.level,'voxels')||strcmpi(params.level,'subsetvoxels')||strcmpi(params.summary_measure,'eigenvariate'),ROIdat(:,rrx)=data;
        end

Even if I deleted my ROIs and just used those several default ROIs like WM, CSF, and PCC, this error still existed.
So I just left grey matter, white matter and CSF in the ROI tab, which let me found that as long as the dimensions of GM, WM and CSF were 1, SETUP could run. But I see that the dimensions of WM and CSF is 16, so what does 

Now I just have no idea what caused this error. Would anyone be so kind to help me out of this? Thanks in advance.

Best regards,
Xinyuan
