Jaakko,
The message about the missing talairach.xfm file can be ignored (unless things stop completely and issue an error message). The code performs a relative path search to find the file if it doesnt find it in the hard- coded path (a historical remnant).
About the Tcl problem, which Linux OS variant is being used? Freesurfer does include Tcl/Tk/Tix/BLT (in $FREESURFER_HOME/lib/tcltktixblt) and 'tksurfer' is actually a wrapper script which performs the setup to use those libs, then calls tksurfer.bin. This is intended to prevent conflicts with other Tcl/Tk installations.
Maybe you have an existing Tcl/Tk installation that is conflicting and not handled by our wrapper script. Before sourcing the freesurfer setup file (SetupFreeSurferEnv.csh), can you type the following:
env | grep TCL env | grep LD_LIBRARY_PATH which tclsh which tclsh8.4
This will tell you if you have an existing installation.
Also, are you trying to run tksurfer locally, or over a network connection, like VNC?

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":

The setup script ran flawlessly, producing the following output:

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/ fmri/fmrihome/dti/software/freesurfer/lib/tcltktixblt/lib/tk8.4 ./lib/tk8.4 ./li b/tk8.4 ./library ./library ./tk8.4.6/library ./tk8.4.6/library

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
