Hi, I can not understand why I am getting the following error message. It is obvious that I am missing a something: I see the histograms with ".ls" but when I try to do a Divide I get errors. Can anyone point out what I am missing here? thanks much. ahmet ---------------------------------------------------------------- root [6] .ls TROOT* Rint The ROOT of EVERYTHING OBJ: TH1F hgain_EM normalized EM gains : 0 at: 0x8b66030 OBJ: TH1F hgain_HA normalized HA gains : 0 at: 0x8b66450 OBJ: TH1F hGC_EM EM Geometrical correction from MC : 0 at: 0x8bb7ac0 OBJ: TH1F hGC_HA HA Geometrical correction from MC : 0 at: 0x8bb8370 OBJ: TH1F hCC_EM EM Calibration correction : 0 at: 0x8bb87a0 OBJ: TH1F hCC_HA HA Calibration correction : 0 at: 0x8bb8bb8 OBJ: TH1F h200 : 0 at: 0x8bb8fd0 OBJ: TH1F h201 : 0 at: 0x8bb93e8 OBJ: TH1F h300 : 0 at: 0x8bb97d0 OBJ: TH1F h301 : 0 at: 0x8bb9fa0 OBJ: TH1F h400 Integral of bins 10-24 EM : 0 at: 0x8bba468 OBJ: TH1F h401 Integral of bins 10-24 HA : 0 at: 0x8bba870 OBJ: TH1F h500 Integral of bins 10-32 EM : 0 at: 0x8bbb150 OBJ: TH1F h501 Integral of bins 10-32 HA : 0 at: 0x8bbb568 OBJ: TH1F h2000 Calibration Coeff.mean of bins 10-24 EM : 0 at: 0x8bbba80 OBJ: TH1F h2001 Calibration Coeff.mean of bins 10-24 HA : 0 at: 0x8bbbeb0 OBJ: TH1F h3000 Calibration Coeff.mean of bins 10-32 EM : 0 at: 0x8bbc2e0 OBJ: TH1F h3001 Calibration Coeff.mean of bins 10-32 HA : 0 at: 0x8bbc710 OBJ: TH1F h4000 Calibration Coeff.Integral of bins 10-24 EM : 0 at: 0x8bbcb40 OBJ: TH1F h4001 Calibration Coeff.Integral of bins 10-24 HA : 0 at: 0x8bbd350 OBJ: TH1F h5000 Calibration Coeff.Integral of bins 10-32 EM : 0 at: 0x8bbd778 OBJ: TH1F h5001 Calibration Coeff.Integral of bins 10-32 HA : 0 at: 0x8bbdba0 OBJ: TH1F hhh400 : 0 at: 0x8bbdfc8 OBJ: TH1F hhh401 : 0 at: 0x8bbe3a0 OBJ: TH1F hhh500 : 0 at: 0x8bbe778 OBJ: TH1F hhh501 : 0 at: 0x8bbeb50 OBJ: TH1F hemADC : 0 at: 0x8bbef28 OBJ: TH1F hhaADC : 0 at: 0x8bbf310 OBJ: TH1F hemADC2 processed : 0 at: 0x8bbf6f8 OBJ: TH1F hhaADC2 processed : 0 at: 0x8bbfef0 root [7] hemADC2->Divide(hemADC,hGC_HA,1,1); Error: Symbol hemADC is not defined in current scope FILE:(tmpfile) LINE:1 Error: Symbol hGC_HA is not defined in current scope FILE:(tmpfile) LINE:1 *************** Ahmet Sedat Ayan Physics & Astronomy Dept.
