reading netcdf-4 ubyte datatype [message #74692]

Hi,
I'm having trouble reading a netcdf-4 file with "ubyte" type data in
it. I believe that "ubyte" is a valid netcdf-4 datatype (unsigned
byte) and should just correspond to IDL "byte" type, but ncdf_varget
tells me that datatype is "unknown'. I get this error msg:

% NCDF_VARGET: File format error. Varid 5 has a unknown type

I don't think it is a file format problem, as I can read this file
just fine with Fortran, and it also passes the CF conventions checker
cleanly. Does anyone know how to read the "ubyte" datatype from a
netcdf-4 file using IDL?
Thanks,
Alison Walker
