Instances are ordered to put similar structures near each other. Select one instance to see its 3D structure. Selecting two or more instances will show their superposition, but only chains with identical numbers of observed nucleotides will superpose well. Large structures are slow to display; this tool is not designed for that.

Heat map of mutual geometric discrepancy, in Angstroms per nucleotide. The ordering in the heat map is the same as in the table. The colorbar ranges from 0 to the maximum observed discrepancy. Click above the diagonal to select a range of structures, below the diagonal to select two structures.
