FYI, when trying any version > 6.0.3, e.g., 6.0.4, 6.0.5, et al, you will get:
FATAL: While pulling shub image: Failed to get manifest from Shub: The requested manifest was not found in singularity hub
6.0.6.1 is current as of Dec 2022.
Also if you run the example:
singularity exec --nv singularity-fsl_6.0.3.sif eddy_cuda9.1
singularity exec --nv singularity-fsl_6.0.3.sif eddy_cuda9.1
