[Gate-users] Error with the command "setMaterial NaI"

[Elnur Sadihov]

Hello, Gate users!

I use virtual Gate. I am simulating CT system. I've written several
mac-files based on the example_CT. I am trying to run the main macro but an
error appears:

[Gate] Sorry, error in a macro command : abort.

NaI is presented in GateMaterials.db. The file Materials.xml is in the
current directory where all macros are, and also in the parent gate
directory.

Are there any ideas on the solution of this problem? Thanks in advance!

Below I'm attaching the macro file scanner.mac which is responsible for
setting the geometry of the system, and also the main file bencmarkCT.mac:
