If I run on two root files with reconstructed B0 (/u/ec/ursl/d/output/breco-112101/misc/dstar-brecovubmix120001.root or /u/ec/ursl/d/output/breco-112101/misc/dc-brecovubmix120001.root) just after a root file with charged B's I get the message 0 number of B many time (for each event) and the mes is always 5.274 (?, from the mes plot). I don't see the message if I run on that file alone or after a root file with B0. Daniele
