[Apology for cross-postings] Announcing a workshop at the CNS2015 meeting in Prague, Thursday July 23: Open Collaboration in Computational Neuroscience http://opensourcebrain.org/docs/Help/Meetings#CNS_2015 Building and analysing biophysically and anatomically detailed neuronal networks is a complex and time consuming task, which ideally involves researchers with a range of backgrounds and technical skills. However, most labs cannot expect to have all of these researchers present at any given time. This can lead to stalled projects, lost data and software and needless repetition of experimental and computational work. A number of initiatives have been started which address these issues. Some are creating public resources with freely available data to constrain such models. Others are using best practices from open source software development to encourage building and sharing of models in a collaborative environment. This workshop will serve as an informative introduction to these projects as well as a discussion forum for getting feedback and gathering requirements from the community for the developers of these initiatives. There are still a number of slots available for *5-10 minute lightning talks*, so if you are involved in a project in this area and wish to publicise it, please get in contact. *Confirmed speakers:* Jan Antolik (CNRS) Collaboration in neuronal modelling: model sharing, workflows and provenance Nicholas Cain (Allen Brain Institute) Resources for Open Collaboration at the Allen Brain Institute <http://www.brain-map.org/> Padraig Gleeson (University College London) NeuroML <https://neuroml.org/> & the Open Source Brain Initiative <http://opensourcebrain.org/> Adrian Quintana (University College London) Geppetto <http://www.geppetto.org/>: online visualisation & simulation for neuronal models Michael Sonntag (LMU München) The NIX Project: Comprehensive Storage of Neuroscience Data and Metadata <https://github.com/G-Node/nix> Matteo Cantarelli (MetaCell Ltd) OpenWorm <http://www.openworm.org/> Aurel A.
