Re: problem: "zero field" label and vcMinMagnitudeF

Dear Silvio,

Yes, the problem was fixed on June 20, but this was after our V6.1.0-beta release, so that version doesn't have the fix.

If you really need a fixed NCL now, let me know offline. I will need to know the output from:

   uname -a
   gcc --version
   gfortran --version
   ncl -V

If this is a Mac system, then also:

sw_vers -productVersion

Thanks,

--Mary
