B.2 Running an OPeNDAP Client

If you use one of the pre-compiled, out-of-the-box, OPeNDAP clients, you will need no additional software to run OPeNDAP. However, you can use the "GUI" feature of the OPeNDAP client²⁵ by installing the following software. We recommend this, as it provides useful information about the progress of data transmission or error conditions.

Tcl/Tk

The Tcl language and Tk libraries are available from http://www.scriptics.com. You should install the entire package, including the wish interpreter program²⁶ and the expect package. The wish interpreter is part of the Tcl/Tk core distribution package. This package is also available in the OPeNDAP distribution, but the one available from the Tcl site may be more current.
