[Support #RWW-823329]: Re: Data Exception Error Fixed

Hi Tony-

Here are some other suggestions:

- turn off caching using the Edit->Preferences menu and
then uncheck the "Cache Data in Memory" option under
the Data & Formats tab.  This will keep the IDV from
holding a copy of the data in memory and instead will
have to read it from disk each time you access the
same variable.  Unless you are doing mutiple plots of
the same variable, you will have a memory savings at
the expense of disk access.
- You can still run your grid at full resolution, but
use the Data Source's Properties editor to decimate
the grid under the Spatial Subset tab.  So, you can
keep a larger domain, but skip every n'th point.

You could start the IDV, set the region of interest and
then use the File->Default Bundle->Save option to save
that as your default view.

Also, for now, if you are going to write a script to
concatenate the files together, you could add a line
in there to automatically delete the index.  If you are
always using the same name for the concatenated file,
the index name will always be the same.
