Re: [idvusers] File Naming COnvention

Hi Jim,

I have a group of 25 grib files that are produced by a locally run model. The files name do not end in grb or grib. So in the "Data Choosers" tab I select "Aggregrate Grids By Time" for "Data Source Type". I then go to the directory where the grib files are stored and the files are listed in the window. I then select "Grid Files(netCDF, GRIB,OpeNDAP,GEMPAK)" for the "Files of Type". The listing goes blank as if there are no grib files in that directory. So I have to assume that IDV is looking for a particular filename format. I'm not wanting to change the filename format that the model spits out as other progrmas use these files.

Yes, the "Files of type" uses some pre-defined patterns in the IDV. You can always leave this as "All Files". Semantically, the IDV just uses the Files of type to filter what is shown in the File chooser. It uses the "Data Source Type" to actually figure out what kinds of data you have selected.
So is there a way to configure IDV to look for the particular naming convention that I have or what?

Attached is a datasource.xml file that you can install as a plugin (Tools->Plugin Manager: File menu or copy the file to:
~/.unidata/idv/DefaultIdv/plugins

You should edit this file to include the regular expressions that match your file naming conventions.
