error: No method 'findVariable' with matching signature found for class 'ucar.nc2.dataset.NetcdfDataset'.

good morning ...

I tried to follow this tip:

url = 'http://geoport.whoi.edu/thredds/dodsC/bathy/srtm30plus_v1.nc';
nc = ncgeodataset (url)
topovar nc.geovariable = ('top')
s.lon = [-71.2 -69.9]
s.lat = [41 42];
s.h_stride% = [2 2];% get every other value
g = topovar.geosubset (s)
imagesC (g.grid.lon, g.grid.lat, g.data); axis xy; colorbar;
title ('SRTM (m)')

and run the file aprece the following error:

>> g=topovar.geosubset(s)
??? No method 'findVariable' with matching signature found for class

I ran the following:

url = 'http://geoport.whoi.edu/thredds/dodsC/bathy/srtm30plus_v1.nc';
nc = ncgeodataset (url);
topovar = nc.geovariable('topo');
s.lon = [-71.2 -69.9];
s.lat = [41 42];
s.h_stride = [2 2];  % get every other value
g = topovar.geosubset(s);
imagesc(g.grid.lat, g.grid.lon, g.data); axis xy; colorbar;
title('SRTM (m)');

The above code ran fine. I'm unable to duplicate your error. It looks like your 
syntax is not quite correct. Can you try my code snipped above and see if it 
works for you.

Working through the syntax issues seems to clear it up.  Brian's code works 
fine.

First errors were on: 

     topovar nc.geovariable = ('top')

Which has the equals sign in the wrong place, then misspells 'topo'.

I'd say close this issue.
