Possible motifs include V, PPI V, lambda, delta, and bifans. Motif frequencies can be analyzed in the context of gene duplications to explore the impact of small-scale and whole-genome duplications on gene regulatory networks. Additionally, GRNs can be tested for motif enrichment by comparing motif frequencies to a null distribution generated from degree-preserving simulated GRNs. Finally, users can calculate the interaction similarity between gene pairs based on the Sorensen-Dice similarity index. <div class="figure"> <img src="vignettes/motifs_vignette.png" alt="Network motifs and functions to identify them.
