Hai felim,
              If your file is in grb format, use 'cdo gradsdes2 filename.grb' which will give you the descriptor file. Other wise you can try grib2ctl program.

Hi, 
I'm new to the CDO program and GRaDs,my GRaDs version is 2.0.a8.I have some forecast outputs that i have been trying to view with GRaDs, i tried to make a descriptor file in order to use the GRaDs software, i used the "gradsdes1" command but it only makes a descriptor file with 2 variables out of the 49 that each forecast contains, also it states that  "lonlat grid unsupported, skipped variable var49 " and so on for the other 47 variables.

The forecast output is for a rotated grid which i know can lead to difficulties,  When i check the discriptor file only 2 variables are available, also when i try to display it in GRaDs it states "entire grid undefined" set to missing data

Just looking for help as to what i need to do  to rectify the problem, or any advice would be much appreciated, thanks in advance,
regards
