Hello, You need to modify the line reading: FSLDIR=y/fsl to FSLDIR=/usr/local/fsl and then resource the .bash_profile. To answer your other question, the fsl course data is not included with the main FSL distribution ( due to its size ) and can be downloaded from: http://fsl.fmrib.ox.ac.uk/fslcourse/ Kind Regards Matthew > When I typed "less ~/.bash_profile", I found the following: > > # FSL Setup > FSLDIR=y/fsl > PATH=${FSLDIR}/bin:${PATH} > export FSLDIR PATH > . ${FSLDIR}/etc/fslconf/fsl.sh > > No idea the meaning... Perhaps the environmental variable was not set > properly by the installation program? > >
