ErmineJ Tree View

Tree view post analysis

  • Double-click on a node to view the details. Single-click on a node to expand its immediate children.
  • Right-click (MacOS:option-click) on a node to get more tools.
  • If you have more than one result set loaded, you can choose the one to show in the tree using the “Results” menu.
  • Terms which have no genes in your annotations are hidden by default but can be shown using the pop-up menu.
  • Your user-defined groups are shown as a separate “pseudo-branch” of the tree.

What the icons mean

The icons indicate the state of a node, as well as that of its children. This makes it easier to see that even if a term is not “significant”, it has a child term that does. To expose the sub-tree at a node, right-click and select “Expand this node”.

  • littleSquare – The group is not significant, and has no significant children
  • littleDiamond – The group is not significant, but it has significant children
  • goldCircle – The group is significant, but has no significant children
  • goldCirclePurpleDot – The group is significant, and it has significant children

Where “significant” means after multiple test correction.


  • Only one path to the root is shown per GO term. Other immediate parents of each term are only shown in the tool-tip for the term. To see an accurate representation of the GO hierarchy, use the GO consortium’s web site, also accessible through the context (pop-up) menu.
  • Attempting to expand large sections of the tree is slow; you may see an error message saying it was cancelled.
