Dear Ralf,

Thank you for your suggestion, too.
I aggree that I need to vertex fit absolutely to get the vertex position in reco level.
But I was working at generate level in order to see efficiency drop region by using true vertex information after reconstruction.

By the way, you mentioned that I can use simply any kind of track properties just after the Kalman filter (so let say before back propagating, you mean?) with theAnalysis->ResetDaughters(kshort);

I am not sure for this functionality, what should happen with reset of daughter in the analysis code?
Why I need to do that? A bit more detail please!

Best wishes,
Donghee
