Ok, I see. You meant CF-1.6, not CDF-1.6. The file format is netcdf-3 (also known as "classic"). I am not a MATLAB expert, but the fact that it recognizes the CF-1.6 convention says it should be able to process it. Unfortunately, if you have MATLAB errors, then you will need to contact MATLAB support. Sorry. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: HHB-377746 Department: Support netCDF Priority: Normal Status: Closed
