How can I read in up to 25 columns of data? > > 2. I am running the Qt beta ROOT version 4.00.07 for Windows XP and get the following error message when I launch ROOT: "Error: cannot open file "_string" FILE:(tmpfile) LINE:2" > "*** Interpreter error recovered ***" > Any ideas? > > Thanks. > > Wolf -- Graduate Research Assistant // High Energy Physics Lab kordosky@hep.utexas.edu // University of Texas at Austin kordosky@fnal.gov // ph: (512) 471-8426 (RLM Lab, Office) (512) 475-8673 (ENS Lab)
