Hello all,

I want to thank everyone who responded to my request = for information.=A0 All responses were very helpful.=A0 Thank you all = again.

=A0

I think Molden can = do this as a series of gifs.

-Cory =

=A0=A0 =

"Molden" (available for nearly all platforsm, although UNIX is supported best) = can read g98-outputs and animate the frequencies. A movie can't be saved, as far = as I remember....

but

xmakemol and xvibs = together are nearly perfect:

xvibs extracts = the=A0 normal modes from a g98 output

(avbailable as src = code, infos in the header) and puts them in *.xyz files,

that can be read = > from (beside molden and much other programs) by xmakemol (LINUX tool, = available as src, bin, rpm, deb,...), which has the possibility to save animations. It = creates *.xpm files, which

can be concatenated = together to become an mpeg or animated gif file. I guess the "Help" = function or webpage woll tell more....

All software is = best found by a www search with e.g. "www.google.com".

If you can't find = something, let me know and I'll help you.

Bye

Elmar

I use molekel to = create rendered frames from g98 output, and then some

sgi tools to = convert them into a movie.

The molekel people = have done the same thing here: http://www.cscs.ch/molek= el/gallery.html

You could probably = find free tools or write scripts to catenate and

convert from image = frames to a movie format if you don't have this

already; here for = example: http://www.gnu.org/d= irectory/graphics/anim/

Or by screen = capture while molekel is playing:

http://www.gnu.org/directory/v= id/

Molekel has a = reputation for beautiful rendering and ease of use. If you find a handier or more = attractive solution, please let me know.

Hope this = helps,

Hi,

I have used Jmol =

http://jmol.sourceforge.net/

to visualize = vibrational motion.

Best = regards,

Per-Olof = =C5strand

Molden can animate = frecuencies and you can save and view them via the opengl utility moldenogl. = Sometimes it results in weird molecules with unbelievable bonds, but, when it works = well, the result is pretty good.

Dear = Don,

Maybe molden is not = a very fancy program, but it is quite a good help when calculating with = gaussian (and it is free!). If you have it, you can enter the program and use the = second button from the top (it looks like a photographic camera). This command = creates one gif file each time the frame being displayed changes, so just = animate the vibration ("normal mode" button) click this button and wait = for a while (just don't forget to click this button again, if you don't want = to completely fill your disk!). Then, you can make an animated .gif with = any graphic program (photoshop...). Another way (smarter) of doing this is = to open molden with the command:

"molden -w = 1" and animate the normal mode you want. Then, you open again with molden the = file "freq.dat" that was created in the previous step, click the = camera button and animate the sequence with "movie". Then, you exit = the program and process the *.gif files thus obtained.

Hope it = helps.

Hi = Don

I know exactly the = problem you're having, I had the same thing myself last year. I use gOpenMol http://www.csc.fi/gopenmol/ - = it isn't the easiest thing in the world to learn to use, but if you download the = manual (I can't attach it as it is 10Mb) then look at page 203 for the = animation instructions. In fact the whole of app. 5 (starts on page 195) is what I = use all the time. I found that I had to use the stand alone version of = xvibs. If you download it and install it and then can't figure out how to get it = to work then let me know and I'll try to write out how I do it for animations of vibrations. I guess that you're wanting to have them in talks - the mpeg = is usually under 200kb in size so it is really good.

Hope this is of = help to you

Hi,

to animate = frequencies we use molden. But for recording the video to play it in presentations we = found is useful to use HyperCam (not HyperChem of course!). This is a general screen-recorder like a screen capture tool which recorders videos with = up to 15 frames per second (I think). If your machine is fast enough (pentium = 600) to animate the frequencies and record them at the same time you will get a standard avi file which can be edited with any video editing = software.

Regards

Eike = Huebner

HyperChem with = HyperCam should be able to do this from a checkpoint file. I think you can save = it as an *.avi file to input into PowerPoint. I did this a couple of years ago = with a simple CO2 mode.=A0 The movie is not

great quality, but = the graphics were acceptable.
