Ward, I tend to forget which HDF5 version is required, so check the documentation, which currently says 1.8.8 <http://www.unidata.ucar.edu/software/netcdf/docs/getting_and_building_netcdf.html#build_default>, not 1.8.9. If you know the requirement is for 1.8.9, could you do what's needed to fix the docs? address@hidden> wrote: > New Staff Reply: corrupted netcdf file > > Hello Samy, > > I apologize for the delayed response.
