Nick,

Thanks very much. I will do as per your suggestion. I am new to Linux and Ubuntu.

If I am not bothering you too much. I read an article where they compared the results
from Freesurfer's different versions and about using different OS and concluded saying that
use the same version and do not upgrade while in the middle of the study. My collaborators are using
Freesurfer 5.0 and I will be helping them in processing the data (sharing the data processing and analysis)
so is it ok to use use 5.3.0 or 5.0 is recommended.

Thanks very much again
Venkat

Venkat,

Your system appears to be 32bit distribution, as indicated by 'i686' in
your output string, but the freesurfer you installed is 64b, indicated
by 'x86_64' in our filename.  So you will need the 32b dist:

freesurfer-Linux-centos4-stable-pub-v5.3.0.tar.gz

Also, v5.0.0 is pretty old, I'd recommend v5.3.0.
