Hi Jeremy,

I tried to edit HPSECalCommissioning's compat.xml by changing

<layout beamgap="20.0*mm" nx="46" ny="5" dface=“ecal_dface">

to

<layout beamgapBottom="20.0*mm" beamgapTop="50.0*mm" nx="46" ny="5" dface="ecal_dface">

but JAS+Wired doesn’t show the detector at all after that.  
And I didn’t get any log messages.

Any ideas?

-Nathan

That is a lot more complex to implement and will require writing a new detector model that is structured differently than the current one.  (I added a JIRA item for this, but I don't know when we will be able to do it!)
