Heatmap demonstrating the problem.

Dear Geant4 Developers,

I placed 3 scoring meshes in a water sphere this way:

        /score/create/boxMesh xy_plane
        /score/mesh/boxSize 20. 20. .5 mm
        /score/mesh/nBin 400 400 1
        /score/quantity/doseDeposit Gray1 gray
        /score/close
        /score/list

        /score/create/boxMesh xz_plane
        /score/mesh/boxSize 20. .5 20. mm
        /score/mesh/nBin 400 1 400
        /score/quantity/doseDeposit Gray2 gray
        /score/close
        /score/list

        /score/create/boxMesh yz_plane
        /score/mesh/boxSize .5 20. 20. mm
        /score/mesh/nBin 1 400 400
        /score/quantity/doseDeposit Gray3 gray
        /score/close
        /score/list


When I plot the dumped data I can see the other two scoring meshes. Please see the image attached. The other two scoring meshes are the cross on the heat map.

Is this expected behavior?

Thanks for your help!

We found that if we set the resolution to be the same in each direction, than the cross disappears.

For example:
        /score/create/boxMesh xy_plane
        /score/mesh/boxSize 20. 20. .5 mm
        /score/mesh/nBin 200 200 5
        /score/quantity/doseDeposit Gray1 gray
        /score/close
        /score/list

        /score/create/boxMesh xz_plane
        /score/mesh/boxSize 20. .5 20. mm
        /score/mesh/nBin 200 5 200
        /score/quantity/doseDeposit Gray2 gray
        /score/close
        /score/list

        /score/create/boxMesh yz_plane
        /score/mesh/boxSize .5 20. 20. mm
        /score/mesh/nBin 5 200 200
        /score/quantity/doseDeposit Gray3 gray
        /score/close
        /score/list
