WebThe co-occurrence network was built with Cytoscape (version 3.5.1). Spearman’s coefficient of >0.5 was defined as “co-occurrence”, and Spearman’s coefficient of <−0.5 was defined as “mutual exclusion”. A P-value of <0.05 was defined as statistically significant. All statistical analyses were performed in R software (version 3.4.0). WebJun 15, 2024 · To facilitate easy public use of this model, an R package 'cooccurNet' is presented here. Results: 'cooccurNet' includes functionalities of construction and analysis of residues (e.g. nucleotides, amino acids and SNPs) co-occurrence network. In addition, a new method for measuring residues coevolution, defined as residue co-occurrence score ...
