The tracing community

As of July 2018, this community has two components: (1), a group tracing in a collaborative 'walled garden' in a CATMAID server hosted by the Bock lab, in 'open lab notebook' fashion; and (2), independent tracers who have downloaded the dataset and are running their own CATMAID (or whatever) servers. Laboratories participating in (1) include:
  • Erin Barnhart - Columbia University
  • Davi Bock - University of Vermont/Janelia Research Campus
  • Gwyneth Card - Janelia Research Campus
