How do I interpret the differences in node colors and sizes in the default network?

In the default network generated by MetaboAnalyst, the size of the nodes are based on their degree values, with a big size for large degree values.

The color of nodes are based on

  • Node type (distinct colors are applied for genes, metabolites or disease nodes)
  • Node betweenness centrality values (different gradients within each node type).
  • When user switches to Expression View, the color will be based on their expression values (if available).
