Genes in each module were analyzed using ToppCluster to identify enriched GO biological processes and GO molecular functions. ToppCluster used the Fisher exact test for enrichment and reports an “enrichment score” that is the −log10 of the BH-adjusted P value. Because many GO annotations are related, representative terms were selected to summarize the enrichment results. M11 was not enriched by any GO biological process but was enriched by GO molecular functions. –, No enriched GO function was identified.

The ISGs in each module were identified by using Interferome.
