[DAS] Configuring a valid MAPMASTER?

[Chris Cole]

Hi,

I have a functioning ProServer install that works fine with Ensembl, but 
I'd like to get it working with IGB as well. However, it fails to load 
as it has a 'Missing MAPMASTER element'. I see I need to specify a URI 
to a known MAPMASTER source, but I've no idea how.

The server is for Arabidopsis data and I've found the Ensembl DAS 
sources for plants, but which can I use as a mapmaster?
http://plants.ensembl.org/das/dsn
Or am I barking up the wrong tree?

Any pointers much appreciated.
Cheers,

Chris
