Skeleton operations

Operations with the Context Menu

WEBKNOSSOS has a context menu that can be opened via Right Click. This context menu offers useful context-sensitive information and most operations should be available through it:

Example operations include (but are not limited to):

• Clicking on a node:
  • measuring the path length of the active node to the selected node
  • measuring the path length of a tree
  • node deletion
  • marking a node as branchpoint
  • tree merging & splitting
  • extracting shortest path to a node
  • hiding tree
• Clicking on a volume segmentation:
  • compute or load its 3D mesh
  • flood-filling the segment (assigning a new ID)
• Clicking on the background data:
  • Creating a new node or tree
  • Creating a new bounding box

Merging / Splitting Trees

Common tree operations include splitting and merging trees.

• Tree splitting can be done in two ways:

• Delete the node at which to split. This can be done by right-clicking a node and choosing "Delete this Node". If you have enabled Classic Controls, you need to select (SHIFT + Left Click) the node first and then delete (DEL) it.

• Delete an edge between two nodes. Select the first node (Left Click), then right-click the second node and select Delete Edge to this Node. If you have enabled Classic Controls, you need to select the first node with Shift + Left Click and then click on the second node with SHIFT + CTRL + Left Click on the second node of the edge to delete this connection.

• Tree merging works similarly to edge deletion but will create a new edge between two previously unconnected trees. Select the first node and right-click on a second one to choose Create Edge & Merge with this Tree. When using Classic Controls, the second node needs to be selected with SHIFT + ALT + Left Click to create an edge between the two.
