[Gate-users] Energy windows

[Marc Chamberland]

Hi,

I think Gate is case sensitive. So try to change "singles" to "Singles" on the following lines:

/gate/digitizer/window1/setInputName singles
/gate/digitizer/window2/setInputName singles
/gate/digitizer/window3/setInputName singles

If that does not work, then I do not know.

Good luck!
Marc
