CCL: SUMMARY: Software to animate frequency calc



Hello all,

 

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

 

 

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

"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  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

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/molekel/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/directory/graphics/anim/

Or by screen capture while molekel is playing:

http://www.gnu.org/directory/vid/

 

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,

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.

Regards

Try gOpenMol

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.

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.  The movie is not

great quality, but the graphics were acceptable.
