description: Hello Alexandros, I experienced some problems with vertex resolution and loss of efficiency, too, recently, in the analysis of the Ds mesons, which I am working on. I had used the trunk rev 25345. Due to some geometry update, apparently it looks there was a bug in that trunk revision. Now I updated my trunk to the rev 25545, as Stefano suggested some days ago; and it looks much better. This is maybe the problem that you found(?) Talk to you later, Elisabetta
