Dear Colleague, We would like to announce the alpha release of the Brain Modeling ToolKit (BMTK), developed at the Allen Institute for Brain Science: https://github.com/AllenInstitute/bmtk. BMTK is a python-based software package for building and simulating models of neuronal circuits. It supports simulations at four levels of resolution (biophysically detailed, point-neuron, population statistics, and machine intelligence) by providing wrappers to tools such as NEURON, NEST, diPDE, and TensorFlow. This is an alpha release and we are working on creating more extensive documentation and tutorials. Meanwhile, we are very much looking forward to hearing feedback on the existing functionality. If you could try out the package and let us know about your experience, that would be very much appreciated! At this early stage, we are happy to work closely with you to help you get started on using the BMTK. Please email the lead developer of BMTK, Kael Dai, at kaeld@alleninstitute.org<mailto:kaeld@alleninstitute.org>, or to me, at antona@alleninstitute.org<mailto:antona@alleninstitute.org>, with any questions. A good place to start is the user guide: https://alleninstitute.github.io/bmtk We are looking forward to your feedback! Many thanks, Anton.
