[lsst-dm-stack-users] Generating registry.sqlite3

This would have been clear had I properly read the explanation on the Trac site. My apologies! Everything is clear now as far as what the registry file does.

When I run this, it generates a registry file, but it also gives the following in the standard output: 

. ... started
. ... 0 processed, 0 skipped, 0 unrecognized
Cleaning up...

So it doesn't look like it's processing anything. Is this expected?

I'm trying to preprocess an SDSS fpC file, but it doesn't seem to be reading in the specific data IDs:

 WARNING: No data found for dataId=OrderedDict([('run', 1033), ('camcol', 2), ('field', 111), ('filter', 'g')])

My guess is that the registry file isn't being generated properly, so the pipeline doesn't know how to process the IDs.
