<Apologies for cross posting> We would like to announce a major new version of the Open Source Brain platform (v2.0) we have been working on which has a range of new features for you to try: https://v2.opensourcebrain.org. You can create cloud based, persistent workspaces which contain models and data from a number of sources (https://v2.opensourcebrain.org/repositories) including: - All *OSBv1* projects incorporating NeuroML and PyNN models - All *ModelDB* entries - All *BRAIN Initiative DANDI Archive* datasets containing NWB files Inbuilt applications which can open these workspaces include: *- NetPyNE UI*, a 3D graphical application for neuronal simulations (NeuroML compliant) *- NWB Explorer* for opening and visualising data in NWB files *- JupyterLab*, a full interactive Python environment, with a number of computational neuroscience, data analysis and machine learning packages preinstalled. Full documentation is at https://docs.opensourcebrain.org and a Guided Tour introducing the main features of the platform is here <https://docs.opensourcebrain.org/OSBv2/Guided_tour.html>. We are very keen for new users to try out our platform. Please note that you will require a different username/password for OSBv2 from OSBv1. We are also very happy to make dedicated resources available on the platform to support classes/tutorials/computational neuroscience schools. The Open Source Brain Initiative aims to: - Make neuroscience experimental data and computational models from around the world easily findable in a single location - Provide a free to use, collaborative, web based, interactive computing platform that integrates state of the art software tools for accessing and working with large scale data sets and computational models. - Encourage the use of standards for making research outputs more FAIR (Findable, Accessible, Interoperable and Reusable): OSBv2 supports NeuroML for models and NWB for data. Please get in contact if you would like to help us with any of these goals! Regards, The OSB Team
