Hi Zhoujun, The operation of converting an NcML file (or any CDM dataset) to a NetCDF-4 file is something that can be done from the command-line [1]. If you would like to do it programmatically, I suggest just following the lead of the ucar.nc2.write.Nccopy.main() method [2], which is what is being invoked when converting from the command-line.
