Hello Hermann,

Thank you for the bug fix. I integrated inside that PR and rebase everything on master.

Unfortunately, the test test019_linac_elekta_versa_with_mlc_phsp_source.py does not work because inside the phsp used by that test, the PDGCode and Weight keys are not present, they are not necessary for the test. Do you have a solution?

Thank you Thomas

Hi Thomas,

the mentioned tests work again. The code complained that the PDGCode is not present although it was not needed. I have fixed it (e.g. added an exception to only complain if something is missing if it is really needed.).

Best, Hermann
