problems with cdf files

[antonio rodriguez <arv@xxxxxxx>]

Hi,

I have dowloaded some coads cdf files from www.cdc.noaa.gov

The files correspond to a grid of 2º x 2º for example: 4w:6w / 20n:22n

When plotting the file in ferret I get a different longitude axis, from 
40E to 120W !!. I've compared with the output in GRads, and this one 
plots the right longitude. I've checked that the regions are set OK, i.e:

SET REGION/X=4W:6W
SET REGION/Y=20:22

Any idea,

Thanks in advance
