Dear grads users,
I have a monthly precipitation data from CRU covering the period 1901-2006.
I have selected a period within the time series using cdo as follow
example: cdo seltimestep,10/130 cru.nc output.nc

when I try to open the output.nc with grads I have this message

scanning self-describing file:  output.nc
gadsdf: SDF file has no discernable X coordinate.

when I check with: 

ncdump -c output.nc
I have something like that:


netcdf output {
dimensions:
        x = 194 ;
        y = 201 ;
        time = UNLIMITED ; // (120 currently)
        nb2 = 2 ;
.
.
.


data:

 time = 29599, 29630, 29658, 29689, 29719, 29750, 29780, 29811, 29842, 29872, 
    29903, 29933, 29964, 29995, 30023, 30054, 30084, 30115, 30145, 30176, 
    30207, 30237, 30268, 30298, 30329.....
}

I note that the longitude and latitude don't appear but the time appears. It is like the operation on cdo has
removed the longitude and latitude.


NB: I can open the original file (the one with the complet time series) with grads without any problem.

Can anybody help me, thanks in advance.
