[Gate-users] No Coincidences output

[山中 琢]

Thanks for the quick reply.

I forgot to mention the type of the scanner. It is a double head scanner as
you said.
I tried the minSectorDifference as 1, but it didn't work neither.

When I use the benchPET.mac in the benchmark folder of gate_v6.1, it gave me
Coincidences output, so now I'm trying to see my system with the
cylindricalPET system with the double head.

Thanks.
