Hi Ngoaka
no, you don't need to set the origin of the image. Just point recon-all at a single slice from the correct dicom series (of a highres T1-weighted scan) with the

-i <full path and file name of dicom slice> -all -s <subject id that you pick>

and you should be good to go

cheers

Dear all,


I'm new on FreeSurfer.
I want to calculate cortical thickness, hippocampus volume from MRI images
(obtained from ADNI).

After installation, I tried recon-all. >> Only this process, can I obtain
cortical thickness and hippocampus volume?

And someone told me that I have to set origin of the image of each case
using SPM program.

I want to know that is it necessary?


Thank you​ for your kind attention


Best Regards,

Ngoak​
