[gradsusr] Data not being displayed

[Marcus Morgan]

I have had this problem occasionally.  Usually it's because the undefined
values in your .nc file is set as -8e+38.  You can change the default
undefined values of the .nc file to be 99999.0, as per your .ctl file,
using programs such as CDO.  You could also change your .ctl file UNDEF
parameter to -8e+38 and see if that works for you.
