Marc,

After sourcing the $FREESURFER_HOME/SetUpFreeSurfer.csh file, add this line:

unsetenv TCLLIBPATH

This is what is causing the conflict with FSL's TCL libs.

Hello, I am in need of some help. I have spent the last two days trying to get fsl and freesurfer to play well together. I have the newest version of FSL installed and it works perfectly. I then installed freesurfer per the instructions listed in the wiki. After these steps, freesurfer works, but fsl won't open. I get this error message:

I tinkered with the setupfreesurfer.csh and the freesurferenv.csh files and got it to list FSL_DIR as usr/local/fsl but the program still wouldn't work.

If I comment out the two freesurfer lines in my .cshrc file, fsl works perfectly once again. My only guess is that there is a problem with both fsl and freesurfer having tktcl libraries. But my understanding of UNIX, etc is somewhat limited. Below I have also attached my .cshrc :

#!/bin/tcsh set path = (/usr/X11R6/bin $path /sw/sbin /sw/bin /Users/marcyelle/bin) set prompt="`hostname -s` !% " source /sw/bin/init.csh source /usr/local/rsi/idl_5.6/bin/idl_setup setenv IDL_PATH "<IDL_DEFAULT>:+/usr/local/rsi/idl_5.6/local_lib" setenv FREESURFER_HOME /usr/local/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.csh setenv FSLDIR /usr/local/fsl source ${FSLDIR}/etc/fslconf/fsl.csh setenv PATH ${FSLDIR}/bin:${PATH} unsetenv LANG

Thank you in advance for your assistance, I need it! Sorry for the long email, I simply wanted to give you as much info as I could. Take care.
