BioExcel Building Blocks (BioBB) is a collection of interoperable building blocks built as portable wrappers on top of common biomolecular simulation tools (see BioExcel webinar #48). The interoperable building blocks can be easily joined together assembling complex computational biomolecular workflows, and can be shared thanks to its integration with the Conda Packaging system, ensuring reproducibility. This webinar will present two different ways of using the BioBB library/workflows remotely: BioExcel Building Blocks Workflows (BioBB-Wfs), a web-based graphical user interface (GUI) offering access to a collection of transversal pre-configured biomolecular simulation workflows assembled with the BioBB library. BioExcel Building Blocks REST-API (BioBB-API), a compilation of REST API endpoints offering programmatic access to the collection of biomolecular simulation tools included in the BioBB library. Molecular Dynamics setup, docking, structure modeling, free energy simulations and flexibility analyses are examples of functionalities included in the tools presented, all of them accessible through common web browsers and REST API calls, voiding the need for tools installation (remote access).
