Sequence-based prediction of homomeric interface contacts for three CASP13 FM targets: A) interdigitated trimer T0953s1 and prediction by group RR106; B) dimeric interface (isologous) of T0968s2 and prediction by group RR036; and C) hexameric subunit T1022s1 and prediction by group RR164. Contacts in the target assembly are shown in the upper-right of the matrix and predicted contacts are shown in the lower-left, with transparency levels proportional to the contact rank. Contacts are classified based on the nature of the interaction: interface (orange), tertiary (blue), tertiary and interface (shared, purple) or prediction false positives (no contact, black).
