External Email - Use Caution        

I am basically looking for a way to create an average of the labels for the L  subcallosal cingulate cortex (SCC) and then make an average of the labels for the R SCC across all subjects  and use these 2 average labels as a mask to see if the average label L SCC and average label of R SCC aligns well with with the actual location of the L and R SCC for each individual subject. Do you know of a better way to do this?

Hi Carlos,

 

mri_concat concatenates input .mgz files.

 

The following command will output C.mgz with A.mgz as the first frame, and B.mgz as the second frame, assuming both A and B have only one frame.

mri_concat --i A.mgz --i B.mgz --o C.mgz

 

I’m not sure that is what you are looking for.

 

Best,

 

Yujing

        External Email - Use Caution        

Good afternoon,

 

I would like to verify that the subcallosal cingulate cortex (SCC) segmentation of my subjects are correct. I want to do this by creating an average label of the left SCC and an average label of the right SCC which I can then map onto each subject.

 

If I save these labels from each subject as a volume (.mgz) and then run mri_concat on the left SCC labels (.mgz) and then on the right SCC labels (.mgz), would this accomplish my desired goal?

 

Tks,

 

Carlos
