Adapting GenePairFinder to identify gene pairs with divergent expression in a pair of clusters?

[laracbusby]

Hi,

Thanks for such an awesome tool to integrate across species datasets!

I am curious whether there would be a way to adapt the GenePairFinder function to identify gene pairs that are 1) expressed differentially between a pair of clusters (1 from each species) and 2) contribute negatively to the correlation score between that pair of clusters.

I am interested in identifying genes that are expressed in one species but not the other in a specific pair of clusters - i.e., what are the gene level differences which contribute most significantly toward the lowering of a correlation value between two clusters?

Thanks so much!
