[Sphenix-maps-l] MVTX TGeoNode Name Change?

Hi MVTX experts,

I updated my macros repository this morning and it seems that the Acts tracking no longer works because of a change in the MVTX geometry. Previously we were accessing the TGeoNodes in the geometry by iterating over the TGeoVolume and accessing the MVTX objects by getting the nodes that had “av_1” in their name. This now returns no valid MVTX nodes, which means I’m guessing that the node names were changed. Perhaps this is related to the recent addition of the MVTX services into the geometry?

Does anyone have a pointer as to what happened here? Just for clarity, the way we were accessing the MVTX nodes previously can be found here in lines 807-826.

Thanks for any help you may have,

Joe Osborn
