If your OS is also 64bit, then you can use the x86_64 dist of freesurfer. You can confirm this by typing:

uname -m

and you should see:

x86_64

4GB is plenty of RAM and 320GB is plenty of disk-space.

Hi, I want to use freesurfer to quantify cortical thickness, and I want to use the software under Linux fedora core 4. My computer's equipment is Quad-Core processor Intel Q6600, DDR2 memory 4GB, Sata2 disks 320G, GeFORCE8600. Which version do you recommend? i386? or x86_84?
