Macromolecular Contacts Tool. Analysis of residue-residue contacts in biomolecules (proteins, DNA). A GUI-based JAVA (platform free ) code that computes and displays residue-residue contacts for multiple sets of macromolecular snapshots, e.g. coming from various MD trajectories.

Visualization of electrostatic interactions between titratable groups in proteins . Visualization (and analysis) of clusters of electrostatically coupled groups and their interactions in proteins.
