The Viking Annotation System

  • Viking is a multi-user, web-based collaborative management system for images and volumes which allows users to view multi-terabyte datasets, annotate images with their own schemas and summarize the results. Viking was developed by Dr. James Anderson at the Marc lab for use with the first retinal connectome RC1, assembled using Automated Transmission Electron Microscopy (ATEM) and Computational Molecular Phenotyping (CMP), and is available at
  • To get an idea of how Viking works click here. You can also download a movie (2.5 minutes) which highlights basic features: VikingDemo.mp4
  • Viking browses images collected and registered into a volume. The Scientific Computing Institute’s image registration tools (IRIS) are available at CONNECTOME RESOURCES
  • Network visualization tools can be seen here.
  • Network export tools can be seen here.
  • To build connectomes for visualization with Viking, see Nornir.
