[ferret_users] *urgent help* needed: loading opendap data via ferret

[Haoping Yang <Haoping.Yang@xxxxxxxx>]

I am having trouble to load temperature data from some OPeNDAP servers 
such as 
http://ensembles.ecmwf.int/thredds/dodsC/ocean/ecmwf/eg/thetao.html. 
From the web browser, one can open this link and see the data 
structure. The variable 'thetao' has 5 dimensions: *[time = 
0..575]*[ensemble = 0..4][level = 0..32][latitude = 0..178][longitude = 
0..359]. The dimension 'ensemble' is useless to me. When I try to load 
the data via ferret, ferret uses 'ensemble=0..4' as the time dimension 
and no temperature data can be loaded. Ferret assumes the data has four 
dimensions instead of five. I don't know how to remove the  dimension 
'ensemble' and let 'time' to point to the axis 'T' (index 'L'). There 
must be some tricks to load this data. I guess it might be something 
like "yes? use/ORDER=.... URL" and could be very easy for some ferret 
experts. Please help me. Thanks
