[Castor-users] Forgotten zeros in histogram data format

[Etienne Auger]

Hello fellow CASToR users,

Do you know what happens if, for Gate simulation output data that I converted myself into CASToR data in histogram format, I forgot to put 0 (zero) in the histogram bins (LORs) that had no coincidences? In fact, these bins were just never created in my conversion code. Does CASToR automatically put a zero in them when it sees they are not initialized or am I then reconstructing wrongly, with weird stuff possibly happening? The images I reconstruct in this (possibly bad) manner do not exhibit visible artifacts, but I still wanted to know if this method is fundamentally wrong.

Thanks for your insights,

Étienne
