+ // A particularity has been introduced here :
+ // if gime->Event(ievent,"R") is called branches with the current title are read, the current title
+ // being for example give in AliPHOSPID(fileName, title)
+ // if gime(Event(ievent, "RA") is called the title of the branches is not checked anymore, "A" stands for any
+ // This is a feature needed by PID to be able to reconstruct several times particles (each time a ther title is given)
+ // from a given set of TrackSegments (with a given name)
+ // This is why any is NOT used to read the branch of RecParticles
