Reply to Ableton reanalyzing tracks

At the moment I have edit the warps marks of a track, by setting a new start-point (set 1.1.1 here) and used the function "wrap form here straight". But I like to reanalyzes the track so that Ableton sets the warp-marks for me so I can edit where it is necessary.

I tried to reanalyzes the tracks by clicking the root folder and "Wrap From Here (Start at ... BPM)" but that doesn't seems to work. And there isn't a *.asd file present in the root folder.

Does anyone know how to reanalyzing the tracks?
