    Hi Fernando,<br>
    <br>
    With GATE 6.2 the MultipleScattering process no longer exists.<br>
    For electron and positrons, you have to select
    "eMultipleScattering"  in your physics list:<br>
    <br>
    /gate/physics/addProcess eMultipleScattering<br>
    <br>
    Hope this helps<br>
