Using ATAC->RNA linking is most biologically meaningful, but reduces the number of modalities we have to provide context. Let's think about how we can define cell-specific contexts. One possibility: define a set of genes/peaks which provide cell "state" but we don't care about therir regulation. Another possibility: use dim-reduced version of the full data, leaning into the interpretation of cell-specific networks as locally-linear views of a global network.
