Hi Lia,
So running STT reconstruction for eta_c with commented SttMvdGemTracking->SetPdgFromMC();
on the same data set I have the same efficiency around 15% as with this option on. So at least if this is a real drop in efficiency with STT and not a statistical fluctuation it's not the problematic place.
