Hi all FreeSurfer Experts, I'm a young researcher, PhD student of the University of Padua with a degree in Mathematics.
I'm trying to use FreeSurfer for analyze a 3D image MRI, DICOM format (I have NIFTI too) to calculate brain volume.

I downloaded the software from your site following the instructions for a Linux CentOS 4.

Now my questions are:
I have a classical MRI 3D image file, how do I send the files to FreeSurfer?
What are the instructions that I have to write in the bash?
Is there a GUI to calculate brain volume?

Any help is appreciated,
Thanks!

Michele.
