q4md-forcefieldtools an Internet site devoted to the development of empirical force fields such as AMBER, CHARMM, GLYCAM and OPLS. It combines resources (programs, database and tutorials) useful in atomic charge derivation, force field library building and force field parameter development.
q4md-forcefieldtools stands for tools related to atomic charge values, force field libraries and force field parameters required in 'QM-MM-MD' simulations. q4md also stands for 'Charge for MD simulations'.

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 is an Internet service designed to derive RESP and ESP charges and to build force field libraries for new molecules and molecular fragments.


R.E.DD.B. is a database of RESP and ESP charges and force field libraries 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 submission has to be carried out in R.E.DD.B.


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


FFParmDev allows developing new force field parameters.
