Jim,
Dave Brown pointed out that I was making your question harder than I
needed to. In order to force Nio to read your data as an HDF-EOS file,
you can just append a ".hdfeos" suffix to the end of the name in the
open_file call. I believe Dennis Shea already showed you this from an
NCL script.
For example, if the file is called "file.hdf" and you want to read it
as an HDF-EOS file:
filename = "file.hdf"
Nio.open_file(filename + ".hdfeos")
Nio will first look for a file called "file.hdf.hdfeos", and if it
doesn't find this, then it will look for a file called "file.hdf", and
it will try to open it as an HDF-EOS file.
This applies to any file you have that you want to open with
Nio.open_file: you can always include the suffix if the original
filename doesn't have one, without having to rename your original
file. Another example: if you have a GRIB file called "U78559", you
can open it with:
Nio.open_file("U78559.grb")
