Hi Bruce,
In fact, have 2 differents surfaces of pial surface. I would like to save my surfaces in volume to be able to calculate the dice score between the two.
Cheers
Lucille

Hi Lucille
what do you mean by converting a surface to the volume? What do you want to do with it? What volume would you like to convert it to?

Hi, My name is Lucille and I'm really new with Freesurfer : My questions are very basic, sorry. I just start a project in segmentation of cerebrum. For converting a surface in volume. I would like to use mri_surf2vol but for that I need a volume registration file . For creating that file, I would use autoreg-sess. In documentation, it is said that : 'The volume registration file contains the matrix that maps XYZ in the reference anatomical to XYZ in the functional volume' My question is : what here, represent the anatomical reference ? The functionnal volume ? Secondly, for autoreg-sess, the arguments are the subject name and the subject directory. I think the registration I need to create must be between my 2 volumes, so should I use the subject name and subject directory for my 2 subjects ?
Sorry,I am really messed...
Cheers Lucille
