[Gate-users] genericRepeater: Hit With Wrong Head

[Miriam Dixon]

Hi gate-users,

I want to make a four head SPECT system using the genericRepeater. At the
moment, I have a two head system with each head 76 degrees apart and I
would like to put a second pair in opposite the original pair. Because the
four heads are not evenly spaced around the ring, I cannot use the ring
repeater to do this, so I am trying to use the genericRepeater. However,
when this setup is run, I get the following error:
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (1): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (1): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (3): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (3): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (2): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (2): ignored!
[GateToProjectionSet::Fill]:
Received a hit with a wrong head ID (2): ignored!

Also, the projection data collected appears to only be that of one head,
rather than having projection data from all four heads.
I have attached a .zip file with a short example to show the problem, in
case anyone has an idea on how to fix the problem. I am using Gate v9.0.

Cheers,
Miriam
