Re: [ferret_users] change the pseudo variable name

[Paul Young <paul.j.young@xxxxxxxx>]

Hi Prescilla,

You can refer to T by using quotation marks (can't remember whether  
double or single, and can't find in the documentation at the mo). E.g.

fill/l=10/k=1 "T"

Of course, you can also rename the variable with nco operators (http://nco.sourceforge.net/ 
). E.g.

ncks -v T infile.nc just_T.nc   							!dump temperature from large file
ncrename -v T,temperature just_T.nc					!rename T to temperature

Hope this helps

Paul
