Help: ChemComps


The CTD ChemComps page presents chemicals with comparable sets of interacting genes as the subject of the detail page.

Similarity Index

Similarity (or comparability) is measured by the Jaccard index, which is defined as the size of the intersection of interacting genes for chemical A and chemical B divided by the size of the union of those genes:
Jaccard Index formula: A∩B / A∪B

Chemical

The chemicals with comparable interacting gene sets as the subject of the detail page.

You may view the common interacting genes between the subject of the page and a chemical of interest by clicking a link in the right-hand column. This link will take you to results generated using the VennViewer tool.
