[Gate-users] NEMA_IEC_2001 phantom in example_PHANTOM_SOURCE folder

[Marc Chamberland]

(I forgot to reply to the mailing list in my original message.)

Hi Sam!

The error is telling you that your maximum radius is smaller than your minimum radius (6 < 10). Since the macro file does not specify the minimum radius for sphere10, then the minimum radius must be getting a default value when a sphere is created.

If you look in the source code (file GateSphere.cc), you'll see that it is indeed the case: if you don't specify a minimum radius for a sphere, it gets a default minimum radius of 1 cm.

So, just manually add a minimum radius in the macro file.

Cheers!
Marc
