[ferret_users] choosing a grid point
Dear ferret users
Thanks to all who replied but my problem still exists. I'm
trying to create a harmonic analysis of tides. I chose some coordinates
say California, England (1W, 54N ), Philippines and I want to have the
plot of sea level [depth in meter] wrt time [days]. I can do so by
choosing the location using ncview as seeing what the corresponding
values of i and j at that position might be, but I want the exact
coordinates, as 1 W, 54 N for Immingham, England.

/yes? SET DATA levitus_climatology

The above mentioned weblink shows some similarity but doesn't work in my
case, when I execute the first 3 lines as shown above, gives me the
following error
/yes? show data/full

Help needed. Thanks.
