 ### 4_Co-occurrence_network.R
-This script first defines the function "co_occurrence_network" to generate a filtered gml-formatted network file based on all pairwise Spearman's correlations and FDR-adjusted P-value calculation and filtration, and then uses input abundance table to generate co-occurrence network which can be visulized in Gephi (https://gephi.org/) and calculate network topological properties.
