The genus trace: a function that shows values of genus (vertical axis) for subchains spanned between the first residue, and all other residues (shown on horizontal axis). The number of the latter residue and the genus of a given subchain are shown interactively.

The genus matrix. At position (x,y) a genus value for a subchain spanned between x’th and y’th residue is shown. Values of the genus are represented by color, according to the scale given on the right.

Structure visualization

After clicking on a point (x,y) in the genus matrix above, a subchain from x to y is shown in color.
