Regarding : Unsupported grid type: generic in setonlatbox

Added by ankit bhandari over 3 years ago

Dear Sir

I am using my test_file ti cut a small area out of it I am getting error of "Unsupported grid type: generic". What is the issue with the file, as file is having all the coordinates .

.
cdo sellonlatbox,72.25,75,24.75,22 test_file .nc tt1.nc

cdo sellonlatbox: Unsupported grid type: generic

cdo sellonlatbox (Abort): Unsupported grid type!

netcdf test_file {
dimensions:
lon = 115 ;
lat = 115 ;
time = UNLIMITED ; // (30 currently)

lon:axis = "X" ;
double lat(lat) ;
lat:axis = "Y" ;

Hi Ankuit,

the coordinate values lat and lon do not have the attribute units which let CDO handle it as a generic grid.

Add attributes to file:

ncatted -O -a units,lat,o,c,"degrees north" -a units,lon,o,c,"degrees east" test_file.nc

Select region:

cdo sellonlatbox,72.25,75,24.75,22 test_file.nc tt1.nc

Check output file:

Thanks Karin
But again I am getting the same error in my computer. What is the reason?

HP-Pavilion-Notebook:~/Downloads$ ncatted -O -a units,lat,o,c,"degrees north" -a units,lon,o,c,"degrees east" test_file.nc
-HP-Pavilion-Notebook:~/Downloads$ cdo sellonlatbox,72.25,75,24.75,22 test_file.nc tt1.nc
cdo sellonlatbox: Unsupported grid type: generic

cdo sellonlatbox (Abort): Unsupported grid type!

Is this because of CDO version:

As I am using Climate Data Operators version 1.9.3 (http://mpimet.mpg.de/cdo)

Pls reply?

Maybe it is caused by the old version. Please, upgrade to the newest version.
