write ctl file to read netcdf file

[aditsuda jamroensan]

Dear grads user

     I'm trying to write a ctl file to read netcdf
file but I got the error "Contouring: nan to nan
interval inf". Anyone have got this error? Here is my
ctl file:

dset /var/tmp/ajamroen/CCTM_e3aCONC.e3a.20020111.nc
undef -99999.0
title  OUTPUT FROM CCTM

endvar
