Dear Eduardo,

Which ones ? If you really need all of them, we can submit them in
R.E.DD.B. right away. All is ready, we just have to submit...

All ? No until they are registered in R.E.DD.B. // a R.E.DD.B. code
has been generated. However, if you provide me the list of the
cofactors you need for your calculations, we can try to provide these
co-factors to your personal email.

For the web, we use Jmol http://jmol.sourceforge.net/.
See the projects in R.E.DD.B.; For instance:
http://q4md-forcefieldtools.org/REDDB/projects/W-46/JavaApplet-1.php
http://q4md-forcefieldtools.org/REDDB/projects/W-46/JavaApplet-2.php
   up to
http://q4md-forcefieldtools.org/REDDB/projects/W-46/JavaApplet-10.php

To create images, we use molekel:
http://q4md-forcefieldtools.org/RED/images/RED.jpg

Then,
VMD, GaussView, Gabedit etc...

Finally, when you submit emails in the q4md-fft mailing list (.
q4md-fft.q4md-forcefieldtools.org) you need to be registered.
Consequently, your last email was not submitted in the q4md-fft
mailing list.

regards, Francois
