TRK11

Thank you! It worked ncks -4 file1.nc file1_4.nc ncks -A -v CPLMASK file1_4.nc file2.nc

I have upgraded nco to 5.0.4 but the error is the same. I have attached file1.nc and file2.nc ncks -A -v CPLMASK file1.nc file2.nc ncks: ERROR cnk_map = nil not yet supported

I am trying to append variable ncks -A -v mask file1.nc file2.nc But the command fails ncks: ERROR cnk_map = nil not yet supported What can cause the error?
