The latest ORTEX (3rd October 2000) can take any Shelx file and create a rendered GIF animation with relatively simple ease. The most recent change is that "View lock is now the default in RASMOV the initial view should be the "widest" possible on y rot."

The following uses the Tetracycline Hydrochloride structure as an example.

In the ORTEX directory, run Oscail to bring up the following starting Window

Oscail Starting Screen

Click on the J (Job name) Icon and change the name of the jobname to tetcy. If not in the \ortex directory where the tetcy.ins file is located, click on the change directory icon and enter this directory. (in this case in the \ortex\tetcy directory)

Changing the Job Name

Before you can render the movie, you must obtain the view of the structure that you wish to render by running ORTEX.

Thus select the Run Job Icon which brings up the main control menu in the ORTEX Suite.

Run Job Menu

Select ORTEX and press OK to bring up the ORTEX graphics. If queried, select defaults

Ortex Graphics

Select the view or lattice pack that makes you happy. In this case, we will go for a single molecule. Go for the initial view with the "widest" possible on y rot if the want the rotation to appear centred and not dynamically rescaling to fit the entire screen.

Playing with the structure in ORTEX

If in an ORTEX submenu, select Start Stick Mode Icon, and then select Exit from the top menu bar to get back to Oscail

Back to Oscail main menu

Select the Start RASMOV Movie Generator Icon to start on the way to generating the movie.

(If the RASMOV Movie Generator detects that you have a cell packed structure, it will prompt whether you wish to use this "ORTEX" generated file. Respond with the affirmative if you wish to use the cell packed structure)

In the Start RASMOV Movie Generator menu

Select the options that appeal to you. In this case, a 192x160 pixel movie, with shadows, and 360 degrees range with no oscillate. Make sure the lock mode is on if you do not want the molecule dynamically resizing to fill up the entire screen.

Setting RASMOV Movie Generator options

Press OK and the GIF movie file will be rendered. At the end, it will prompt whether you wish to use the TIF, GIF and R3D files used to generate the movie. Unless you wish to make use of some of these files, YES might be a good answer.

You can then choose how you wish to view the GIF animation (the default is in your default web-browser)

Prompting to delete excess files and view the GIF animation

If the image does not come out as expected, go back into Raster or ORTEX and modify until the desired results are obtained.

To view the movie, click on the following.

If you obtain an undesired result, play with the options until you get what makes you happy.
