download_data.sh on the STFC cloud

[KrisThielemans]

I don't think download_data.sh can currently pick up data from the /mnt folder.

~/SIRF-Exercises/scripts/download_data.sh -w ~/SIRF-Exercises/working_dir -D /mnt/materials/SIRF/Fully3D/SIRF/ -p
Destination is "/home/jovyan/SIRF-Exercises/data"
Download location is "/mnt/materials/SIRF/Fully3D/SIRF/"
Downloading PET data
/mnt/materials/SIRF/Fully3D/SIRF ~/SIRF-Exercises
Downloading UCL NEMA_IQ data
rm: cannot remove 'NEMA_IQ.zip.md5': Read-only file system
some error occurred. Retry

This is because

SIRF-Exercises/scripts/download_data.sh

Line 140 in 7ee3951

rm -f "${filename}.md5"

I see that the following env variables exist on my instance

SIRF_INSTALL_PATH=/opt/SIRF-SuperBuild/INSTALL
SIRF_PATH=/opt/SIRF-SuperBuild/sources/SIRF
SIRF_EXERCISES_DATA_PATH=/mnt/materials/SIRF/Fully3D/SIRF/

The first is used by examples_data_path (and therefore makes SIRF_PATH unused). The latter seems nowhere used.

Not sure if this still applies, but flagging it up
