Hi,
This indicates that the file /usr/local/fsl/Course/fsl_course_data/intro/structural_brain.nii.gz cannot be opened, probably because you do not have the correct permissions set in that directory. Try copying the structural.nii.gz image to another directory (where you know you have the correct permissions) and see if it works in that directory.
All the best,
Mark
