How to apply the attenuation correction for the ROOT data from Gate simulating?

Dear CASToR Users and Developers,

I used Gate to simulate the Barin PET. When I use the brain_phantom.h33 to perform attenuation correction with the Cdf from the result of ROOT data conversion, it occurs an error. Does anyone know how to perform correctly attenuation correction?

The error message is shown below:

Dear Qin,

The issue seems to come from the "extent of rotation" variable. A numerical value is expected here and apparently it is not the case in the brain_phantom.h33 file you use. However this value is not used currently by castor, so you can either delete this line of provide any value to bypass this error.

Best regards,
Thibaut
