I am using a HP 3396A integrator to collect data from a non-HP HPLC. Data collection and integration appear to be satisfactory but I cannot get the chromatogram replotted with baseline drawn in. Replot with baseline is enabled with ASSIGN 0, E:BASELINE.BAS (Bunched data signal file and processed peaks data files having been saved) but on reanalyzing the saved signal file, after the standard chromatogram and report have printed, I get the error message: "file not found Exception 7101" .
