About OpenWorm

OpenWorm is an open-source project dedicated to creating a virtual C. elegans nematode in a computer. It provides simulation, visualization and data resources, including a worm body simulator that models muscles, soft tissues and fluids, a 3D browser, the DevoWorm developmental project, a NeuroML connectome, and the Geppetto web-based simulation platform. The project states that all code, data and models are open-source under the MIT licence, and coordinates volunteers from around the world through Slack.

Key features

  • Worm body simulator modelling muscles, soft tissues and fluids
  • WormSim interactive browser tool to play with the worm
  • DevoWorm project for developmental processes via data analysis and simulation
  • OpenWorm Browser for 3D zoom, rotate and peel back layers
  • NeuroML connectome mapping every neuron and its connections
  • Geppetto plug-and-play web platform for biological system simulations
Best for: Researchers, engineers, and volunteers interested in open biological simulation and C. elegans data.
Good for
  • All code, data and models described as open-source under MIT licence.
  • Community of engineers, scientists and volunteers from around the world.
  • Offers multiple interactive tools for exploring the worm.
Watch out for
  • Project is ongoing; current tasks tracked via GitHub milestones.
  • Community coordination uses Slack, with access via a volunteer application form.
  • Described as building toward a virtual organism, not a finished product.
