7.2. Predefine Conformation

Activate the right tab in order to switch to the conformation mode.

On the right panel, you will find some major options. You can either undo several of the changes, which you may need to use quite frequently. You can also restore the initial conformation, as it was when entering the conformation mode. You can also reset the conformation to PDB file defaults. Another couple of buttons can be used to reset the camera to some fixed positions.

Editing the conformation

Before you can change anything, you'll have to pick one or more atoms that you want to move. You can select/deselect single atoms by left-clicking on them. A double left-click into the background deselects all. Another option is to use rubberband selection. Hold down the ALT-Key in order to draw a rubberband and release it afterwards. Use the left mouse to rotate the camera in the meantime, to reach all of your requested atoms.

Example of a selection performed by rubberband



There are two different ways to move atoms:


The following image shows an example of how the right carbon-tail of a lipid could be elongated by using a stepwise combination of
picking atoms -> picking a rotation center -> rotating :

After a little more work, this lipid could look like this:
