[kepler-dev] GARP actor issues

[Timothy McPhillips]

Hi Russell,

I've never used the GARP actors or workflows, but I'd be happy to try  
to reproduce the problem you're seeing and help track down the problem  
(assuming no one else knows the answer to your question already).

Can you send me enough information to reproduce your environment (OS,  
location of Kepler installation, etc), along with the input data file?

Thanks!

Tim
