\item presence at least of one experimental solved structure by X-ray diffraction of a biological assembly with homo-oligomers (containing the domain) with a good resolution (< 3 \AN)   \end{itemize}  The Since the  quaternary structure signals are likely to depends on the chains domains architecture.   In architecture, in  order to be sure to include all the different biological assembly that are at the time experimentally  at disposal we compare the DCA co-evolutionary signal with different several  PDB structures informations. structures.  On this """ point  some remarks are necessary. We collect all PDB with a biological assembly that contains homo-oligomers of the pfam domains selected.  We create a map between the alignment positions and the 3D inter-residues real positions for each pfam - PDB.  To do so we extract the real positions between residues:
