When intending for a single ROMS file to serve as the data source, it is easy to change files. Simply select New File from the File menu and then navigate the file choice dialog.

When intending for a directory of ROMS files (possibly not all of them) to serve as the data source, simply select New Directory from the File menu and then navigate the file choice dialog.

You will subsequently be prompted for a regular expression to use to narrow down your list of choices. See the section called directory for details.

Just like changing single files as an input source, one can change URLs as well by selecting New URL from the File menu and then supplying the appropriate URL. This option is probably easier to use from the matlab command line.

To quit rslice, select Close from the File menu.
