Hi all,
to answer your questions about GEANE: geane is able to track any particle (so also particle with charge different from +1 and -1 and neutral particles).

I will check with prof. Rotondi the interface to be sure that everything works fine: it surely works for charge +1 or -1,
it should be working also for other charged tracks (I made a quick test and it seems right) and it surely does not work for neutral particles (since we store as first track parameter q/p and in that case q = 0).

By the side of geane it should be enough to use, as Ralf said, the TMath::Nint(Float_t) function if we want to have an integer charge (or to go back to double if we decide to).

Best regards,
Lia.
