I am able to import the network into Cytoscape. Now I am trying to find the hub microbes in the network based on Betweenness Centrality and Closeness Centrality.

Just some more queries;
1) How should I import edge attributes (correlation & P-value) as local or shared?
2) How can I do filtering based on cor and p-value (edge attributes) and how to color positive and negative edges?
3) How can I identify the hub microbes in a network (based on network topology calculation)?

Many thanks,
