Session Selection

The ``Session Selection'' panel always appears first when starting any classification task, with the exception of Class Labelling, Class Editing and Aggregate.

The rest of the classification tasks must have a session loaded before they will start. Class Editing and the Aggregate panel will honour any session information if present, but can work equally well without it.

The ``Session Selection'' panel contains a scrolled list of previously saved classification sessions.

Each row in the list consists of three different items. The first is a number indicating the channel in which the data is stored. The second item indicates what the channel is used for. This item can either be a Training Channel or Classification Result. The third item is a user entered description of the session. This description is entered using the Session Configuration panel.

In addition to the list describing the sessions, there are five action buttons:

Accept: This button will use information associated with the selected channel to define class names, class descriptors, class colours, and input channels. Accept is disabled if there are no sessions saved on the current file.

New Session: This button will start a completely new session (ignore existing sessions).

Cancel: This button cancels the classification setup.

File ...: Selecting this button will open ``Database File Selection'' panel to select new file.

Help: This button will provide help information on this panel.

The sessions are stored on the database file as metadata associated with either the Training Channel or Classification Result Channel. A description of the metadata tags is described in the Session MetaData Format topic.
