Visualization problem of latitudes and longitudes of WRF out

[eldeyou]

Hi all,
I managed to install WRF using the script ems_install.pl that you sent me.
I also made a first simulation 24 hours. But I don't get out maps with latitudes and longitudes correctly using NCL or grads. Can you help me please ?
Below an example of my simulations outputs.
~/wrfems/runs/west_africa/wrfprd$ ncdump -c wrfout_d01_2015-09-10_06:00:00 |more
netcdf wrfout_d01_2015-09-10_06\:00\:00 {
dimensions:
Time = UNLIMITED ; // (1 currently)
DateStrLen = 19 ;
west_east = 99 ;
south_north = 100 ;
bottom_top = 44 ;
bottom_top_stag = 45 ;
soil_layers_stag = 4 ;
west_east_stag = 100 ;
south_north_stag = 101 ;
land_cat_stag = 24 ;

And if I do on NCL :
f = addfile ("wrfout_d01_2015-09-10_06:00:00","r")
T = f->T
printVarSummary (T)

Variable: T
Type: float
Total Size: 1742400 bytes
435600 values
Number of Dimensions: 4
Dimensions and sizes: [Time | 1] x [bottom_top | 44] x [south_north | 100] x [west_east | 99]
Coordinates:
Number Of Attributes: 6
FieldType : 104
MemoryOrder : XYZ
description : perturbation potential temperature (theta-t0)

I see that my files haven't coordinates.

Thanks in advance for your help !
