Hi James,

I think that you could still use CDO but before the interpolation step, 
just extract the variable from the input file. So, you could use 
following commands (for example, tas variable),

1 - ncks -v xlon,xlat,mask,tas source.nc source_tas.nc
2 - cdo remapbil,destgrd.txt source_tas.nc destination_tas.nc

in this case you might want to check the content of the 'destgrd.txt' 
file. It must contain correct grid information (only one grid 
definition). Otherwise CDO could give type generic error.

I hope it helps,

Regards,
