Re: TChain problem.

Hi Axel,

        if you can look into the: /rooms/greatlakes/ontario/gag/Calib on the clued0 cluster there is my working dir. CalcResponse.C, Response.C and Response.h are the files which I compile in p14.06.01 version. CalcResponse is the binary. PASS2.p14.06.01.list.001 is the file list of the file which I'm trying to process. On the events number 53833 my program is crashed. If I comment

        b_EM->GetEntry(jentry);
in the CalcResponse.C, method forEachEvent() all work successfully right up to last event.

Thanks,

• George.
