<div dir="ltr"><div>Hi gate-users,</div><div><br></div><div>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:</div><div>
[GateToProjectionSet::Fill]:<br>
Received a hit with a wrong head ID (1): ignored! <br></div><div>

I am using Gate v9.0.</div><div><br></div><div>Cheers,</div><div>Miriam<br></div></div>
