When developing tools for CTAT, we used a DataManager to do this sort of thing. 
So the Admin has to download both the tool and the DataManager, and use the 
DataManager to download the large file and put it in the desired location on 
the system.

Hi Brad,

Thank you for your quick reply. I can put the data file to Zenodo so
that I will have a permanent location for it.

As for re-computing the data file locally, it may need several days to
run, so it may be quite inefficient to do the computing. I am
expecting an automatic download of the data file when installing the
package. Do we have a convention to do that? Thank you.

Best regards,
Jin
