Dear Bob,

> Fabulous.

Thanks & sorry for the delay for writting to the list...
I took a break ;-)

I am aware in some conditions the system is unstable. This is  
particularly true when:
- We open two _different_ pages with Jmol applets _in same time_, many  
browsers we tested simply crash.
- Generally, when we open a first time a single page with many  
applets, it is slow, but it works (in some cases, some molecules do  
not show up, never the same). When we re-load the page a 2nd, a 3rd  
time, etc..., the applets show up slower and slower and the system  
finally crashes... This is true whatever he browsers and their  
versions...

The problem is to be able to get reproductive problems with the  
Browsers and their many versions, the Jmol versions and the Operating  
system... We need to work on this, I know. And yes we use a little old  
version of Jmol. We need to upgrade with the latest version of Jmol.

We use mainly Opera, and Firefox and sometimes konqueror (only under  
linux). We use IE under windows only for testing and because people  
use windows.

OK thanks. However, when you have a force field topology database  
(FFTPDB) such as the F-60 project  
http://q4md-forcefieldtools.org/REDDB/up/F-60/ for instance, it is  
more informative to display all the fragments in same time. Now, you  
are right too much is too much ;-) We will release soon bigger FFTPDB  
with 64, 128 fragments and in this case we will have a huge problem ;-)

> Also, I wonder why you want them to spin?

The idea was simply:
- display the charge values & the structures
- display what can be done with Jmol for what we wanted to do

You are right, the user can stop the spinning in this case ;-)
The applet size is also a little too small...
This is once again only for information. If really interested by a  
project, a user can download the project and study each fragment more  
specifically using the system he wishes (Jmol, VMD or a program to use  
the FFTPDB as in CHARMM or AMBER for instance).

For a force field, we were interested to display the _charge values_,  
themself. Now you are right many other approaches can be applied. Once  
again, we need to work on this with the new features implemented in  
the last versions of Jmol...
I am particularly interested by the MEP feature available in the  
lastest versions of Jmol.

Thanks for your email: It is great to have feedbacks, comments & criticisms...

regards, Francois

PS BTW, we do NOT use Tripos mol2 files to display charge values but  
CML files. These CML files are converted from mol2 files generated by  
R.E.D. http://q4md-forcefieldtools.org/RED/ using a perl script  
available @
http://q4md-forcefieldtools.org/Tutorial/0-Script/mol2tocml.pl
because of the some problems we encountered:

Jmol is described @
