BIGNASim database structure and analysis portal for nucleic acids simulation data


BIGNASim is a comprehensive database system and analysis portal holding nucleic acids MD trajectories and their analyses. The database allows direct access to trajectory data, information about the structure and MD simulation metadata, together with a complete set of analyses performed. Additionally, the database is provided with a flexible NAFlex-based engine allowing users to perform their own analysis pipelines.

BIGNASim uses state-of-the-art technology to deal with BigData management. Two well-known noSQL databases (Cassandra and Mongo) are used to store trajectory coordinates and analyses, respectively. These noSQL databases are queried using REST web services and php drivers.

 To facilitate the access to all information stored, we built a web portal on top of the database system, allowing several ways of accessing the data. The final scheme of the BIGNASim portal is shown in the next figure. Information about how to access data and how to use the portal can be found in these help pages, divided in 5 sections (left column in this page).
