netAna: A tool for network analysis

In present study, a software tool for network analysis is presented. The tool is mainly used to calculate topological properties of the network, detect type of the network, and calculate node centralities of the network. Various network properties include total number of nodes, total number of links, clustering coefficient of network, mean link density of network, connectance of network, skewness of degree distribution, aggregation index of network, variation coefficient of network, entropy of network, etc. Binomial distribution, Poisson distribution, exponential distribution, and particularly power law distribution are used for detection of network type. Node centralities used include degree centrality, closeness centrality, and betweenness centrality.
