Interaction Data:

Our current interaction data is calculated from FR3D. Right now, it is grouped into base base-base interactions, base phosphate interactions, base-sugar interactions, and stacking interactions. We also now include rRNA -- Mg -- rRNA and rRNA -- Amino acid -- rRNA interactions. Interactions are drawn as straight lines. The lines can be colored based on any residue or circle layer. They support color gradients in both directions. However, we can't yet export color gradients. Lines can now be filtered by subtype. Hover over a line with the Alt key held to see more detailed information. Also, check out the Zoom-Aware Lines feature in the Settings.
