Hello Kyle, Please take a look at: org.lcsim.kpix.tbsim.KpixDigitizerDriver in the tbsim module. It provides an example for accessing the MC data in the lcio files. In particular, it extracts the layer number and converts the position to a pixel id. It also makes plots of pixel hits as a function of layer. It just needs to be tied in to the Kpix* writer classes. Let me know if you experience any difficulties or have any further questions.

Cc: Dylan Mead; kpix-beamtest-software Subject: Re: [KPIX-BEAMTEST-SOFTWARE] sim data Hi Norman, I'm able to open and interact with the simulation data you sent us, but I'm not sure how exactly to get at some of the geometry information. It could be that I just haven't found what I'm looking for in the lcsim documentation yet. I have the hits in the file as a list of MCParticles, which contain positional information, but I haven't been able to feed that through the geometry description to get pixel/layer information yet. I can think of ways to do this (particularly for the pixel, which we have methods for finding already of course) but I assumed this information was already in the file, and I wanted to find out what the optimum method was first.
