CaveateDue to problems/limitations in the Delphi development system, Gretep needs Windows to be running in (the normally default) Small Fonts Mode; other wise the window sizes and menus can go very strange. For more information on this, refer to the page on Strange Font Size Problems |
GRETEP (Grenoble Thermal Ellipsoids Plot) is quite simple to use and is obtained from the LMGP program suite site at
http://www.ccp14.ac.uk/ccp/web-mirrors/lmgp-laugier-bochu/.
Load your structure file and get the molecule(s) and view you desire.
|
To create the Metal-Ring bond, click on the top right Set the Ring Middle ICON.
|
Now select the atoms in the ring - then right click. Gretep will then offer you the option of choosing an atom colour and radius of atom. It is best to choose a small atom radius and the colour you will eventually use for your Metal-Ring bond.
|
Gretep will now put a dummy atom at the centre of the ring.
|
Now select the Delete/Add Bond ICON and create a new bond from the dummy atom to the Metal. Then delete the ring Carbon-Metal bonds. Done
|
Customizing bond diameter and bond colourTo change the bond diameter and colour select the Customize bonds check-box which leads to the following screen. Select the colour you wish to make the bonds and the radius.
|
Now click on the atoms which connect the bonds you wish to apply this new radius and colours to change them. Click Right mouse button to exit this mode. Repeat as required. In preparation for generating a Povray image, the background has also been changed.
|
And of course, using the Export image, Export a Povray file options, you can create photorealistically rendered images of the structure.
