View 1
Apply the first saved view to the Workspace. The other four numbered buttons apply the spec-
ified view number. These buttons are always assigned to the first five views listed in the
Man-
age Views
panel. Buttons that do not have a corresponding view are not available.

The
Save View
dialog box opens, in which you can enter a name for the view. The default
name is
view
N. If you want to save views with the default name rather than explicitly naming
them, you can select
Use default name
under
When saving views
in the
Manage Views
panel.
The
Save View
dialog box is no longer displayed, unless you select
Prompt for name
.
The translation, rotation, and zoom are stored in the named view, and the new view is saved in
the project. Once the view is saved, it is listed on the
Restore View
submenu of the
View
menu
and entered into the table in the
Manage Views
panel. If it is in the top five views in this table,
it is associated with a button on the
Views
toolbar.
Named views store information only about the state of the “camera”—the location, angle, and
zoom. They do not store any information about the content of the Workspace. This means that
you can, for example, set up a view of a protein, then at some later point, display the protein
from the same angle with a ligand in the binding pocket.
To restore a saved view, use one of the following methods:
• Choose
View
→
Restore View
→
view-name
• Click the button for the view on the View toolbar (if it has one)
• Select the view in the
Manage Views
panel and click
Restore
In addition to restoring a single view, you can step through a sequence of views manually, or
play through a sequence of views with a given display time
for each view, and you can export a
movie of the sequence of views.
The views that are played can be selected by checking the check box in the
Play
column of the
Views
table. Only the checked views are played with the play controls. These controls also
apply to saving a movie of the views.
To step through views manually, click the
Previous view
or
Next view
button on the
Saved
Views
toolbar, or in the
Manage Views
panel. You can also use the
View
→
Restore View
submenu items to step to the previous or next view.
To play through the views continuously, use the controls in the
Manage Views
panel.
If you want the view changes to be smooth rather than instantaneous, select
View animation
in
the
Animation
section, and set the duration of the animation. If the distances the structures
move are large, you can control when the animation is used by selecting
Limit animation
distance
and entering the distance above which animation is turned off in the
Maximum
distance
text box.

The animation time can be coordinated with the length of time each view is displayed to
produce a continuous movement. The view time is set in the
Pause Time
column of the
Views
table. If you want to set the pause time for multiple views, select them in the table, enter a
value in the
Set pause times to
text box, and click
Set
.
To save a movie in MPEG format with the chosen play list and duration settings, click
Record
Movie
, and navigate to a location and name the movie file. The movie does not record anima-
tion of view changes.
To delete views, select them in the
Views
table and click
Delete
.
Since views are saved in the project, they are not automatically available when you close the
project. To transfer views between projects, you can import and export them, by using the
Import
and
Export
buttons. These buttons open file selectors, in which you can navigate to a
location and name the view file.

Tiling the Workspace
Sometimes you want to see several structures or surfaces in the Workspace separated from
each other, rather than superimposed. This can be done by tiling the Workspace contents,
which rearranges the objects in a grid pattern in the Workspace. There are three ways that you
can tile the Workspace, or tiling modes, which can be selected from the
Tile
submenu of the
View
menu or the
Tile
button menu on the
View
toolbar.
•
Tile by Entry
—This is the default mode, in which each entry
in the Workspace occupies a
separate tile, except for fixed entries, which are displayed in every tile.
•
Tile by Entry Groups
—In this mode, all entries that are in the same entry group are dis-
played in the same tile. This mode allows you, for example, to display several proteins
with their ligands in the Workspace, and use the ePlayer to step through ligands for a
given receptor.
•
Tile by Surface
—In this mode, each surface that is displayed in the Workspace is placed
in a separate tile, along with the corresponding structure. Surfaces for fixed entries are
displayed in every tile, and entries that are displayed in the Workspace that do not have
surfaces are displayed in their own tiles, at the end of the grid (i.e. they are treated as hav-
ing a single surface that is null). This mode allows you to display multiple surfaces for a
single entry in separate tiles, such as molecular orbitals or SiteMap surfaces.
To perform the tiling, choose

Tile
button on the
View
toolbar.
