MDLovoFit: Automatic identification of mobile and rigid substructure in protein dynamics

MDLovoFit is a package for the analysis of the mobility and structural fluctuation in Molecular Dynamics simulations. It allows the automatic identification of rigid and mobile regions of protein structures.

Available at:

For example, it is possible to automatically identifiy a stable region of a protein in simulation in which the protein displays high structural flexibility, as illustrated in the figure on the right. The regions of low mobility are automatically detected by the method.

The software provides, as output, the Root-Mean-Square Deviations of the conserved structures, and of the divergent structures. A trajectory PDB file is output for the visualization of the results.

This software is distributed as FREE software, under the terms of the General Public Licence. Please cite the following reference if it was useful:
