a, Overview of the information flow in AlphaLink. Crosslinks (blue) are embedded and added onto the pair representation (green). Impact of crosslinks shown in red. b, Crosslinks influence the retrieval of co-evolutionary information. They are used as a bias in the MSATransformer. c, The pair representation is updated with information from the MSAs that have been biased with the crosslinks.
