The series cover broad topics related to the latest development of major software packages; their application to modelling and simulation; best practices for performance tuning and efficient usage on HPC and novel architectures; introductory tutorials for novel users and much more.
The webinars include an audience Q&A session during which attendees can ask questions and make suggestions. They are a great opportunity to interact with the main code developers.

Abstract: PRODIGY (PROtein binDIng enerGY prediction) web server predicts of the binding affinities in protein-protein complexes. PRODIGY implements a simple but robust descriptor of binding affinity based only on structural properties of protein-protein complexes, that are introduced in Vangone & Bonvin, eLife (2015). Using the protein-protein binding affinity benchmark of Kastritis et al. 2011 we showed that the number of interfacial contacts (ICs) correlates with the experimental binding affinity. This information, combined with properties of the non-interacting surface (NIS) which have been shown to influence binding affinity (Kastritis at el. (2014)), has led to one of the best performing predictor so far reported on such a large and heterogeneous set of data.
