Hello rooters, I would like to know if it there is a way to add TRFIOFiles to TChains. When I use the TChain::Add("rfio:....") it works correctly or at least no error occurs. But when I want to start a viewer I obtain a segmentation violation. When I use the TChain::Process, the error message Error in <TPluginHandler::ExecPlugin>: no ctor specified for this handler TRFIOFile method, is printed. I tried to add directly the TFiles to the TChain's list of file (using TChain::GetListOfFiles()->Add(tf) method, where tf is obtained by TFile *tf=(TFile *)new TRFIOFile("rfio:...") ) but it does not work. When I use the TFRIOFile alone, all is working correctly. Could it be possible a TRFIOChain Class to chain TRFIOFiles or modify the TChain in order to enable the use of TRFIOFiles? I run ROOT version 3.03/07 on Linux RH7.2. Friendly Daniel CUSSOL LPC Caen Boulevard du Marechal Juin 14050 CAEN CEDEX e-mail : cussol@in2p3.fr Tel : +33-(0)2-31-45-29-73 FAX : +33-(0)2-31-45-25-49
