    Sorry. In the inp file, I forgot to add the direction is negative.

    BEAMPOS 0.0 0.0 200.0
    NEGATIVE

    Even the directon is negative, the result is also the same. And I use
    another way ( subroutine bxdraw ) to take data when muon go to layer from
    air. It still has no output.
    Thanks for your attention!

    Best regards,
    Yung-Shun
