Snapshot of web-based interface for analyzing atomic contact frequencies of HTH-DNA interactions. The protein-DNA binding interface of the Ultrabithorax Homeodomain from D. melanogaster. Green and yellow squares represent residue positions of protein and DNA, respectively, which have been mapped to the universal coordinate system. Edges connecting squares indicate proximity of atoms within a user-defined threshold (shown at five angstroms). For each position pair, the user can interrogate the set of atom-atom interactions observed
