Hi,

The TarckID is the index of the track in the TClonesArray, So it can never be negative, in the Reset function we decided at some point to initialize it with -999 so that if you see this in a hit or a point as a track ID, you know immediatly that something is wrong in the processing hits of your detector!

Mohammad
