Re: I can't access remote ascii data with DODS

[Joe McLean <joe.mclean@xxxxxxxx>]

Hi,

Ferret is DODS enabled such that it has a built-in DODS NetCDF client.  When Ferret sees 'http...' in the ffilename for the command 'SET DATA filename'  it assumes that the data is DODS served and the NetCDF client takes over reading the data.  The Ferret 'file' command expects local files only.

Currently, the server at http://127.0.0.1/cgi-bin/nph-dods/ seems to be down.  What results do you get when you use theh ferret command,'SET DATA "http://127.0.0.1/cgi-bin/nph-dods/asc.dat"'?
