How to use Cytoscape's NetworkAnalyzer tool to calculate network-related attributes, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail, people with this need can come to learn, I hope you can get something.

Igraph tool, can be programmed to deal with network data, the tool is used with large-scale, large-scale data processing. If you only need to analyze network data occasionally, it is more simple and convenient to use cytoscape as a graphical interface tool.

Cytoscape believes that many people have used it, and it is usually used to visualize the network. it is also convenient to analyze the basic topological properties of the network, such as calculating the clustering coefficient value, in cytoscape.

After the cytoscape3.0 version, the NetworkAnalyzer tool is integrated, which makes it easy to calculate common topology properties. You can open the tool through Tools- > NetworkAnalyzer, and the results of the analysis will be displayed in the results panel on the right. The commonly used results are shown as follows

1. Simple Parameter

The clustering coefficient,density equivalent of the network is given, as shown below

2. Node Degree Distribution

For a scale-free network, the degree distribution of the node accords with the power law distribution, and this part can estimate the corresponding coefficient.

3. Shorest Path Length Distribution

Because of the small-world effect utility of the real network, the value of the shortest path in network is very small. As you can see from the figure below, the maximum is 7.

4. Betweenness Centrality

5. Closeness Centrality

In addition, there are many characteristics and attributes that describe the network exclusively in graph theory, which are not shown one by one. Through the NetworkAnalyzer tool, you can quickly get the common basic properties of network.
