Ok, I am confused at this. In your original message you said: > This error occurs when metar2nc.new1 attempts to load records into a netCDF > > file that had just been created using ncgen. I interpreted this to mean that you had your own .cdl file that was being used to create a .nc file using ncgen. In a later message you say: > You can just use the cdl and other files in the distribution. But the cdl files in the distribution work fine for us, so in that sense I cannot replicate the problem. Can you send me the .cdl file that you are using to generate your .nc file? Maybe I can replicate the error with that. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: QEL-795104 Department: Support netCDF Priority: Normal Status: Open
