I recently installed FreeSurfer 3.0.4 for CentOS 4 x86_64 on a server running Fedora Core 3 (w/ x86_64), but ran into the following error upon testing the installation with the command "tkmedit bert orig.mgz":

$ tkmedit bert orig.mgz
Talairach transform /autofs/space/freesurfer/subjects/bert/mri/transforms/talairach.xfm does not exist ...
Loading tal xfm file /home/fmri/fmrihome/dti/software/freesurfer/subjects/bert/mri/transforms/talairach.xfm

The setup script ran flawlessly, producing the following output:

$ source SetUpFreeSurfer.csh
-------- freesurfer-Linux-centos4-stable-pub-v3.0.4 --------
Setting up environment for FreeSurfer/FS-FAST (and FSL)
FREESURFER_HOME /home/fmri/fmrihome/dti/software/freesurfer

MNI_DIR         /home/fmri/fmrihome/dti/software/freesurfer/mni
GSL_DIR         /home/fmri/fmrihome/dti/software/freesurfer/lib/gsl
FSL_DIR         /home/fmri/fmrihome/fsl

I was able to locate the "missing" talairach.xfm file in the appropriate directory.

On another note, I run into the following tcl/tk error when running tksurfer:

Tk_Init failed: Can't find a usable tk.tcl in the following directories:
    /home/fmri/fmrihome/dti/software/freesurfer/lib/tcltktixblt/lib/tk8.4 /home/

    invoked from within
"uplevel #0 [list source $file]"

This probably means that tk wasn't installed properly.

I run into the same error when opening the FSL 3.3 GUI, so I assume the error from FreeSurfer is related. I understood that the latest FreeSurfer is packaged with the required tcl/tk libraries, so this shouldn't be an issue. Any thoughts?

Note: I also installed the standard CentOS 4 (non 64 bit) distribution, but encountered the same problems.

Thanks,
Jaakko
