[Freesurfer] Info FreeSurfer

Hello,

I am working on segmentation of the hippocampus and I need a comparing method.

I am approaching for the first time to FreeSurfer method.

I would like your courteous help.

I have three questions for you:

1 - I have input a MRI-image.nii showing all head. As output I would like a binary image showing only left and right hippocampus. I used the following command:

###

mri_convert FILE_NAME.nii path/directory/NAME_OUTPUT.mgz

recon-all -s SUBJECT_name -autorecon-all

###

How can I extract the required binary image?

2 - Is it possible to comput only hippocampus region (to reduce the processing time)?

3 - Is it possible to give as input only an ristrected region of the subject's head?

Best regards

Andre Tateo
