Introduction

The display table lists all of the loaded data objects, for example each loaded PDB, mmCIF, MTZ or map file is one data object. The name of the data object (usually the file name) is shown in the display table next to a large dot. Each data object can have one or more display objects which are listed one per line beneath the data object name. Each display object is a representation of some selected part of the data with control of the colour and display style. Note that many properties of molecular models such as hydrogen bonds, close contacts and thermal properties are treated as different display objects. For example with one PDB file loaded:

For each display object there are three columns in the table; each column contains a menu, button or slider to control one important property of the display object. For model data these are three menu buttons for atom selection, the colour scheme and the display style of the display object. The columns are labelled for each sort of data object - e.g. 'Atom Selection'.

Note that the Crystal data object and Legends and Images are shown in the table but do not conform to the idea of one data object coming from one data file.

The display object lines can be hidden by clicking the Compact table option on the View pull-down menu. The display objects for any individual data object can be hidden or shown by clicking on the data object line in the table. The down arrow on the right side of the data object line is greyed out if the display object lines are hidden.

The dot menu

Click on the dot next to the data name to bring up a menu which usually has these options:

Hide/Show
Hide all display objects for this data object or show all the display objects that are not themselves hidden. Note that you can quickly toggle hide/show by clicking on the dot with the right mouse button.
Centre on
Put this object in the centre of the screen and fill the screen with it.
Add display object
Add another display object - a new display object line is drawn below this data object name. Note that for molecular models there is Add model display object which adds a display object for coordinates and Add display object which adds surfaces, hydrogen bonds etc..
Move/Stop moving
Drag the object. With the standard CCP4mg mouse bindings depressing the Ctrl key while using the standard bindings for translate and rotate moves an object. Only one object can 'active' and movable - it is indicated by a gold colour highlighting the dot.

Delete the data object

There are usually other data-specific options - particularly note the Generate symmetry mates, Transform coordinates and Animation options on the model dot menu.

The display object icon menu

Each type of display object has an distinctive icon on the left end of its row in the table. Clicking on the icon opens a menu which usually has these options:

Hide/Show
Hide or show this display object. Note that you can quickly toggle hide/show by clicking on the icon with the right mouse button.
Centre on
Put this display object in the centre of the screen and fill the screen with it.
Clone
Make a copy of this display object
Delete
Delete this display object

Configuring the display table

The display table can be configured in the Preferences window: from the the Display folder select User interface options. It is optional whether to show the labels on the table columns and whether to show model numbering on the table.
