This is the code that goes in the user section of the script to specify the FSL version:
# Specify FSL 4.1
FSLDIR=/usr/local/fsl-4.1.0-centos4_64
export FSLDIR
source $FSLDIR/etc/fslconf/fsl.sh
You can also make changes to your profile. Do nedit ~/.bash_profile to find the following:
.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
Then we need to make sure to specify the path when we call the function like
"$FSLDIR/bin/feat" rather than just "feat".
