# when reading ascii files, the user info of the neutrino Trk contains
# the bx,by,ichan,cc variables. Here is a small example :

f = EventFile("/sps/km3net/users/heijboer/./osc_bk/genhen/output/gen_-14_2_v6r10_orca_01.evt")

for e in f :

    e.mc_trks[0].printusr();

    print e.mc_trks[0].getusr("cc");
    
    # or, if you know the index, you can do:
    print e.mc_trks[0].usr[3]
