A web portal for Nuclear Magnetic Resonance (NMR) structures

Amber (Assisted Model Building with Energy Refinement) is a suite of programs that allow users to perform molecular dynamics (MD) simulations on biological systems and to store different calculations. The AMPS-NMR portal is provided by Magnetic Resonance Center of the University of Florence and the Interuniversity Consortium CIRMMP.

The portal was developed with the help of the WestLife and INDIGO-DataCloud projects and supported by the MoBrain Competence Centre, under the EGI-Engage project.

Access policy

The AMPS-NMR portal is free to use upon registration on the website.


The AMPS-NMR portal uses EGI High-Throughput Compute resources.
