The YAMBER force field

YAMBER is a second generation self-parametrizing force field. It has been derived from the AMBER force field (hence the name Yet Another Model Building and Energy Refinement force field) by an optimization procedure first described for the NOVA force field. This time, the optimization targets were however complete unit cells of high resolution X-ray structures. A YASARA movie about YAMBER is also available for download.

A paper describing YAMBER was published in:
