error when running transport.in

[ulyssepoline]

Hi,
Thanks for the amazing work.

I've installted gamos 6.1.0 that was found in the VM.
it works for the tutorial example.

But when trying to run the tissue example and transport.in, I get the following error
/run/initialize

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : FileError
issued by : G4tgrFileIn::DumpException()
Tag not found: :MATEPT_ADD_WAVELENGTHS in file ./world.geom
*** Fatal Exception *** core dump ***
**** Track information is not available at this moment
**** Step information is not available at this moment

-------- EEEE -------- G4Exception-END --------- EEEE -------

*** G4Exception: Aborting execution ***

any idea of the issue?
Thanks!
