Can't find this directory or this file anywhere. Don't know what to look for next. Appreciate some assistance.

Excellent! Many thanks.

Don't find a way to turn on series in the command line catalog generator help message but there is a switch in the GUI. Any thoughts?

Sorry, Idont maintain the catalog generation code, so I have no idea.
