Hi!

I have a question concerning the stepsize limitation and the effects on De/dx. I have plotted the MC-Energyloss over Length
(Pion+, Mometum=0.5 Gev/c, 100 Events)
with Options
"specialCuts+specialControls" in G4Config.C, it looks fine to me, like a landau, as expected:
index.php?t=getfile&id=3993&private=0

I have plotted the stepsizes, too:
index.php?t=getfile&id=3991&private=0

And now my problem: i need stepsize limitation, i turned it on with Option:
"specialCuts+specialControls+stepLimiter" (everything else unchanged)
there is stepsize limitation, like i have befor with the old Release, but my de/dx-MC data is broken:
index.php?t=getfile&id=3992&private=0

(stepsize limitation works:)
index.php?t=getfile&id=3990&private=0

What do i have to do to fix this?

Thanks in advance!

Viola
