bookmark BIGNASim A comprehensive platform including a database system and an analysis portal, aimed to be a general database for handling nucleic acids simulations. BIGNASim allows direct access to individual trajectory data and pre-computed analyses, as well as global analyses performed on the whole database. The database is based on the combination of two NoSQL engines, Cassandra for storing trajectories and MongoDB to store analysis results and simulation metadata. The analyses available include backbone geometries, helical analysis, NMR observables and a variety of mechanical analyses. Individual trajectories and combined meta-trajectories can be downloaded from the portal.
