I am performing a Band calculation which has been done after a SCF calculation on the CeO2-100 cubic system and after the bands.x runs and terminates successfully, the output files says at the last that 'Message from routine punch_plottable_bands too many lines exiting'. The output files CeO2-100.band1 and the corresponding gnu file was created but the CeO2-100.band1.gnu file was empty. For the better understanding I have also attached the input and the output files here. A proper explanation to this problem will be appreciated. Thanks
