Dear Kilian,
I used your input and Flair to make a check and as you can see from the attached files the errors are identical.
In Flair try to clean the data files produced after the merging and reprocess them again.
Best, luigi

>>> scoring the energy in an air-filled cavity in a waterphantom irradiated by a 1.25 MeV photon beam I habe encountered an interesting problem: Using the USRBIN-card one can score the energy either in the region (called "chamber") or use the R-Phi-Z geometry that exactly matches my region called "chamber". So since I am scoring the energy in the same region (in different ways concerning my USRBIN) I should get the same results. However the results are different: 4.64538e-10 GeV pm 0.0290214% for the region-scoring and 5.15530840E-10 GeV pm 3.25998449% for the R-Phi-Z-scoring.
