[Gate-users] Rotation of a gps source

[Jessica Saiz]

Hi Ida,

I've been trying to figure this out myself - I am using two perpendicular
cylindrical sources, which in v5 is not as easy as one would think.  Up to
this point, I have had to make one of them a voxelized source, which is not
a simple command line rotation, but seems to be the only way to do it.
If anyone knows an easier way, I would appreciate hearing about it also.

Thanks,
Jessica
