Problem with 2 netCDF file whom resolution differ

[Stefan Echeff]

Dear all GrADS users,

I try to maps 2 netCDF file.

The first one is a netCDF file of sat image with high resolution and the
second is a netCDF file with resolution lower than st one.

I did :
sdfopen sat.nc
sdfopen anal.nc

when I displayed the first param for the sat image : no problem
I did
'd sat.1'

when I did try to display prmsl of the second :
'd prmsl.2'

GrADS collapse.

It's not possibleto display 2 files with resolutions who differs ?

regards
Stefan
