Hi,

I constructed a network with igraph showing the connections between bacterial groups in three different systems (suppose A, B and C). Each node represented an OTU/ASV (bacterial group) and edge represented connections between them. Each system formed a hub and showed their respective connections. Now I am interested in knowing the number of nodes, edges in each hub and also degree of connectivity among them. Specifically, I want to know whether A and B are strongly connected than A and C or not. By strong I mean more connections/overlaps/mean degree/density/centralization index/modularity.

Any help will be appreciated. I will be happy to share more information if needed.

Best,

Sandipan
