Introduction

Creating a Presentation

To begin pick Presentation/Notebook from the Tools pull-down menu. If you are creating a new presentation enter a name for it. For a presentation called foo CCP4mg creates a directory foo.ccp4mg_presentation in your current project directory. This directory will contain all of the snapshot and status files that are created.

The presentation interface initially looks like this

To load a snapshot, set up the display as you want it and then click on the Insert next snapshot here frame and select Insert current view/display from the popup menu. The current program status is saved to a status file and a small snapshot image is made and displayed in the presentation interface as shown in the Introduction.

Note that the first snapshot is labelled 00001 and subsequent snapshots will be labelled 00002, 00003 etc.. There is a text entry box under the snapshot in which you can enter a title for that snapshot.

A left mouse double-click on a snapshot picture will restore the status of that snapshot. A right mouse click on a snapshot picture will bring up a popup menu with options to
Restore the display and/or the view saved for that snapshot
Replace the snapshot with the current display status
Set insert to move the insert frame before or after the snapshot
Cut to remove the snapshot from the interface (but note that files are not deleted and can be restored using the Load existing snapshot option in the Insert frame).
Copy to save the snapshot to a buffer which can be Pasted in the Insert frame.

The Action pull-down menu

Next and Previous will load the status corresponding to the next or the previous snapshot.
Exit Exit the Presentation interface.

The Edit pull-down menu

Cleanup old files will delete any snapshot and status files that have been removed from the interface.

Package the presentation will collect all data files referenced in the presentations status files to the presentation directory and change the status files so that they now expect the data files to be in the presentation directory. Optionally compress the directory using a zip mechanism.

The Preferences for creating an html file are described above.

Viewing a Presentation

Note that the internal browser option idescribed below is only available on Linux systems.

Open a presentation using the Open presentation option on the File pull-down menu. If an index.html file exists for the presentation then it will be displayed in the internal browser; otherwise a similar Presentation interface to that show above is used. In the standard interface you can change the scene by:

• Selecting Next or Previous from the Action menu.
• Double clicking a snapshot with the left mouse button.
• Clicking a snapshot with the right mouse button and selecting a restore mode from the pop-up menu.

In the browser interface clicking on a snapshot in the html page will restore that status.
