The Connectomics Network Data View

Icon of the Connectomics Network Data View

This view can be used to create a network from a parcellation and a fiber image as well as to create synthetic networks.

The user interface

To create a network select first a parcellation of the brain (e.g. as provided by freesurfer ) by CTRL+Leftclick and secondly a fiber image ( as created using a tractography view). Then click on the "Create Network" button.

• "Use label of end position of fibers" will create a network containing a node for every label a fiber ends in
• "Extrapolate label" will avoid creating nodes using FreeSurfer white matter labels and instead extrapolate in which grey matter label the fiber would end

Additionally you have the option to create artificial networks, for testing purposes. Currently choices are:

• A regular lattice, where each node is placed in a cubic pattern and only connected to its neighbours
• A heterogenic sphere, where one node is placed in the center and connected to all nodes on the shell
• A random network, where nodes are randomly placed on a spherical shell and randomly connected
