On November 23, 2024, R.E.D.Server Dev. was attacked once again by a user!
Fortunately, the security script successfully blocked the attack.
To enhance server security, archive files are now either modified or removed if found uncorrect...

---------------------------------------------------------
On March 13, 2026, R.E.D.Server Development will be closed for about one week for a major update:
The user database will be reset, and users who wish to obtain a private account will need to re-register.
A new version of PyRED will be released; more information will soon be available at:

16 nodes are currently available and ready for use (more can be opened if needed).

The R.E.D. tools

The R.E.D. tools allow RESP and ESP charge derivation, and force field library building for new molecules and molecular fragments.


R.E.D. Server

R.E.D. Server is an Internet service designed to derive RESP and ESP charges and to build force field libraries for new molecules and molecular fragments. Nowadays it is retired.


R.E.D. Server Dev.

R.E.D. Server Development is an Internet service aimed at generating q4md-fft force fields, as a suite of force field libraries and force field parameters. It interfaces the PyRED program.


R.E.DD.B.

R.E.DD.B. is a database of RESP and ESP atomic charges, force field libraries and force field parameters for small molecules and molecular fragments.


R.E.DD.B.2t

R.E.DD.B. Bis & test allows performing blind tests, and learning how a project has to be submitted in R.E.DD.B.


AmberFFC

AmberFFC is a program to convert AMBER and GLYCAM force fields for use with commercial molecular modeling packages.


FFParmDev

FFParmDev allows developing new force field parameters.
