None How do I get proper indices from Readout geometry?

Hi,

I was wondering if someone could help me with getting the right indices for the readout geometry. I have a curved strip detector which I'm modeling as a thin cylindrical partial shell (phi min to phi max), with divisions in z and phi. I've essentially used example N04 for the calorimeter division in z and phi but have changed the radii, phi min/max, and rotated the whole thing in my coordinate space.

I'm using this to track electron energy deposition into the strip. I get a range of z values, but I always get the same phi value out (and I know from tracking visualization that electrons are hitting the whole strip).

I've been trying to get this to work for a few weeks now but I'm not that familiar with the readout geometries. Any tips would be appreciated! Am I not rotating the system correctly using G4Replica? I've attached my ROgeometry, sensitive detector, and DetectorConstruction files.

Thanks!

Cliff
