Take a look at my fsl_sub Mine is for XGrid but you can easily convert it to anything else by changing the command it's sent to. As you will see I had some issues with environment variables and the working location (a lot of cluster software does allow you to specify environment variables per job, some don't) so I created a wrapper script that loads all FSL variables before submitting the job. It works great with both the single jobs and batch jobs. Make sure all your data AND your fsl AND the place you launch the job from is accessible from all systems.
