Conjunction analysis

Submitted by yaosir on Mon, 02/20/2017 - 21:51

Dear Chao-Gan,

I have examined ALFF abnormalities in two type of patients and I would like to examine the shared abnormalities. Acctually, I have tried to use SPM to do a conjuntion analysis, but SPM seemed to require the spm.mat file which I did have, so I was wondering that can I achieve this goal using DPABI? 

Best,

Vincent

You can use Image Calculator.

E.g., (i1>0)+(i2>0)==2

Dear Chao-Gan,

Thank you for your rapid reply. It is a reasonable and straightforward way to illustrate the overlap of significant regions in both maps. However, a possible problem is that the method won't return a peak coordinate, which may be questioned by reviewers.  Do you have any possible solution for it?

Best,

Vincent

That can not be solved in DPABI.
