.calc_IM_scores | Calculate interaction scores for a specific pattern pair
.calc_threshold | Compute the threshold for identifying outlier values or hotspots
.find_genes_of_interest | .find_genes_of_interest Identify genes associated with pattern interaction. This function identifies genes exhibiting significantly higher values of testMat in the Interaction region of the two patterns compared to regions with exclusive influence from either pattern. It uses Kruskal-Wallis test followed by posthoc analysis using Dunn's Test to identify the genes.
