In shape menu the display format of the Ramachandran map can be selected:
| Flat | Tube | Torus | |
|---|---|---|---|
| NOT Energy enhanced |
 |
 |
 |
| Energy enhanced |
 |
 |
 |
Alternatively the above selection can be done with the following hotkeys:
| Hotkey | Action |
|---|---|
| F | Switch to Flat (conventional) Ramachandran view |
| U | Switch to tUbe view |
| O | Switch to tOrus view |
| E | Turn on/off energy surface enhancement |
The appearance of the shape could be selected in the view menu as follows:
| Option | Image | Description | ||||
|---|---|---|---|---|---|---|
| Show texture |
|
Texture holds the color encoded property information on the surface | ||||
| Lighting |
|
Lighting gives some extra plasticity to the shape, but could be disturbing sometimes. It can be switched off if necessary | ||||
| Show grid |  |
The grid of data point is shown as a green line if selected | ||||
| Show scale |  |
The color coded coordinate value grid is displayed if selected for easier navigation on the surface | ||||
| Show labels |  |
The code of the 9 conformers are displayed on the surface if checked |
The displayed molecular property can be selected in the submenu
The angle offset defines the starting point of the second coordinate angles on the tube or torus
| Offset (deg) | 0 | 90 | 180 (default) |

Molecular properties could be loaded from a text file. The coordinate values should cover the 0-360 degree range in 10 degree steps. This file should be in a four column whitespace (space and/or tabulator) separated format:
[First coordinate] [Second coordinate] [Property] [Relative Energy]
After file loading the content of the property column displayed. In this case only the "Custom" property or "Energy" can be selected from the Property menu:
We can switch back to the original dataset by selecting this option
Selecting this menu option displays a simple help on the program controls:
