[ferret_users] memory problem with large file when regredding



Hi all,

I have a 5Go variable at 0.01x0.01 resolution and I would like to save it at a coarser resolution.
My regridding script can be run because it requires too much memory.

Is there a strategy to run i ?
I have tried to save it with different /append calls but cannot figure out
because anunlimited dimension seems to be possible only for time dimension (L).

Here are the simplified lines from my script for a regredding from 0.01 to 0.1°

!============================
use file_0.01.nc     ! mask1 is the variable to regrid

def axis/x=-180:180:0.1/edges/units=degrees_east myxaxis
def axis/y=-90:90:0.1/edges/units=degrees_north myyaxis 
def grid/x=myxaxis/y=myyaxis mygrid
let mask = mask1[G=MYGRID@AVE] 

save/clobber/file=file_0.1.nc mask
!============================

Any help would be appreciated.
Regards

Patrick
