Hi,

We are trying to install Freesurfer on a Linux Fedora Core 6 platform.  We 
downloaded the CentOS 4 platform and the FC 5 upgrade of tksurfer.  We have two 
questions:

1. When we rename tksurfer_fc5 to tksurfer and move it into the Freesurfer 
directory, it is an executable file, whereas the old tksurfer was an executable 
text file.  Do we need to do something to change the file type?  In its current 
state, the tksurfer upgrade does not appear to work.  We tried the command:

tksurfer bert rh pial

and got a "permission denied" message (we are logged in as root).  The message 
was:

/usr/share/freesurfer/bin//tksurfer: Permission denied.

By the way, we have the freesurfer directory in /usr/share/.

2. We seem to be missing a library file of some kind.  We ran these two 
commands to test freesurfer:

tkmedit bert norm.mgz
tkmedit bert orig.mgz

and get this error message both times:

/usr/share/freesurfer/bin/tkmedit.bin: error while loading shared libraries: 
libglut.so.3: cannot open shared object file: No such file or directory

Do we need to download libglut.so.3?

If anyone on this list can answer these questions, please let us know what we 
need to do.

Thanks,
Andrew Bolstad
