Hello Jeremy, Okay, then I'm pretty sure I did it right. I created a file called: /detector-data/detectors/HPS-PhysicsRun2016-Hodoscope-v3-2pt3-fieldmap/SamplingFractions/Hodoscope.properties It contains: samplingFraction: 1.0 The compact.xml declaration for the hodoscope is: <detector id="30" name="Hodoscope" type="Hodoscope_v1" > readout="HodoscopeHits" insideTrackingVolume="true" vis="HodoscopeVis"> So this is correct, right? I also verified that the MC file was run with this detector (HPS-PhysicsRun2016-Hodoscope-v3-2pt3-fieldmap) and recompiled the entire project twice just to be sure.
