TissueNets Program

TissueNets program is mainly used for creating and displaying brain Tissue Networks. In addition, it is also possible to generate and display histograms based on the user's feature selections that are read from the input file. The program also provides users with sample input combination for demo purposes. TissueNets has the following menu selections:

Create Network

In general, the following steps are used for constructing a tissue network:

Step1: Define the Nodes

which create nodes of the network

Step2: Define the Links

which creates links based on k-nearest neighbor algorithm (with exact solution).

Step3: Form the Network

which combines nodes and links and creates a network in XGMML form

Display Network

Once a network is created, TissueNets will help you to display it. After the network is displayed, the user can zoom and rotate the network to get a better view.

If the user has mouse access:

  - scroll wheel zooms in and out
  - left mouse button is used for making selections
  - right mouse button is used for rotating the network

The user also can use the keyboard:

 - key 'x' is used for rotating the network counter-clockwise by the x-axis (10 degrees each time). 

Similarly SHIFT+'x' rotates clockwise by the x-axis.

 - key 'y' is used for rotating the network counter-clockwise by the y-axis (10 degrees each time). 

Similarly SHIFT+'y' rotates clockwise by the y-axis.

 - key 'z' is used for rotating the network counter-clockwise by the z-axis (10 degrees each time). 

Similarly SHIFT+'z' rotates clockwise by the z-axis.

In general, the following steps are used for constructing a tissue network: == Step1: 1- Create Nodes of the network 2- Create Links based on k-nearest neighbor algorithm (with exact solution) 3- Combine Nodes and Links and create a network in XGMML form

Once a network is created, BioNet will help you to display it. After the network is displayed, the user can zoom and rotate the network to get a better view.

BioNet defines two types of networks. The first one is just a standard network consists of nodes and links (edges) defined in a network definition file. The second type of networks is minimum-spanning trees that are generated from network definition files. BioNet gives you options to make proper selections. If the user wants to display a standard network, he/she can also display pyramidal regions by entering a cutoff point. When this option is selected, the average edge lengths that are used in pyramidal region computation will be produced in the file called “pyramidal.txt” which is fixed for now.
