H Marcelo,
The THREDDS Data Server (TDS) can catalog (and serve over HTTP, just
bulk file transport) any file. However, to serve a dataset over OPeNDAP,
it needs to read the data file in through the netCDF-Java library. So
the data file must be in a format supported by the netCDF-Java library.
Unfortunately, at this time GrADS files are not supported by the
netCDF-Java library.
I'm not sure of the details, but I would guess that the GrADS Data
Server (GDS) can serve any GrADS file over OPeNDAP. The GDS also
provides THREDDS catalogs (just add "thredds" to the end of a GDS
directory URL) though the last release I checked had a few glitches in
the catalogs. The GDS can also serve some netCDF files but I think there
are some limitations on that.
Hope that helps,
Ethan

In my way i need that Thredds support GRADS files, but i condn't find
any information about it. In my examples Thredds worked fine with
NetCd - .nc, but i cond't get the same functionality with Grads.

Hi Marcelo,
From our TDS documents page
(http://motherlode.ucar.edu:8080/thredds/docs/), there is an
"Automatic
Catalog Generation using datasetScan" link that describes the TDS
configuration catalogs in some detail. Is this the kind of information
you are looking for?
We have code that can generate DIF records for datasets in a THREDDS
catalog if there is enough metadata in the catalog. This code and
some
code to allow harvesting of the metadata (OAI-PMH) is still in a
prototype stage. It would need some work to get it running again and
make it more robust.
Hope this helps,
Ethan
