[Castor-users] Query related to castor-GateMacToGeom

[Kajal Aggarwal]

Hello,

Thank you for the detailed explanation. I am having troubles to reconstruct
an image for a cylindrical PET system simulated using Gate. I am generating
.geom file and .cdh and .cdf files (attached in this email) for my .mac
file and for the output root file. But the image generated has some problem
(see the screen-shot below). Please guide me where I am going wrong.

Thank you very much for all your support.

Regards,
Kajal
