Comparing two genome annotations I have one-dimentional array (human genome). Also I have two annotations for it, we can think about them as different peaks (it's nucleosome and secondary structures). How can we find correlation and/or causation between this annotations? Currently we are forming hypothesis like "one element is always before other" and statistically testing them. Can we be smarter and use known tools or at least automate this?
You can express the annotations of the genome with a dot plot, x and y represent the two annotations along the genome. The you can summary the result with Spearman correlation coefficient(s) based on whole set of annotations or particular gene families.
