RING-PyMOL is a plugin for PyMOL providing a set of analysis tools for structural ensembles and molecular dynamic simulations. RING-PyMOL combines residue interaction networks, as provided by the RING software, with structural clustering to enhance the analysis and visualization of the conformational complexity. It combines precise calculation of non-covalent interactions with the power of PyMOL to manipulate and visualize protein structures. The plugin identifies and highlights correlating contacts and interaction patterns that can explain structural allostery, active sites, and structural heterogeneity connected with molecular function. It is easy to use and extremely fast, processing and rendering hundreds of models and long trajectories in seconds. RING-PyMOL generates a number of interactive plots and output files for use with external tools. The underlying RING software has been improved extensively. It is 10 times faster, can process mmCIF files and it identifies typed interactions also for nucleic acids. AVAILABILITY AND IMPLEMENTATION: https://github.com/BioComputingUP/ring-pymol.

Simulations for network implementations are an essential component for developing newer and better network solutions and protocols, especially when considering complex scenarios. For instance, networks composed of flying objects coordinating through multi-hop communication represent a foreseeable scenario in our society. The need for analyzing new and tailored solutions for this visionary context passes through the creation of specific tools. To this aim, we present here a novel discrete event simulator deployed to test Flying Ad-Hoc Networks (FANETs) and, in particular, their routing algorithms. In our simulator we have also implemented two different position-based routing protocols for FANETs; their implementation and results are discussed as well.
