Re: addfile() for create new nc file

Hi,

NetCDF doesn't allow you to have strings for coordinate arrays. You
must convert these to 2D character arrays.

Please see the "Coordinate Systems" section of this NetCDF document:

http://www.unidata.ucar.edu/software/netcdf/docs/BestPractices.html

I don't know how you created "season" in your code below, but you can
try converting it to a character array, and use this as your
coordinate variable:

    cseason = tocharacter(season)
   multidata&season = cseason
