Hi Mamen,

are the entries at -1000 or at -999? Because you see, that the default value of the column is -999.0:

ntp->Column("eppx",  (Float_t) eplus[j]->Px(), -999.0f);

In case you call ntp->DumpData() without filling in a value after the last DumpData, the default value will be stored. So you might check whether sometimes (perhaps somewhere else) ntp->DumpData() is called (accidently).

Best,
Klaus
