coordination

This refers to coordination of the vertices of the net. Each structure has a minimum coordination, m, and a maximum coordination, n. (For the great majority of nets m = n). Searching from a to b will retrieve all structures with m greater than or equal to a, and n less than or equal to b.

For e.g. 4-coordinated nets enter from 4 to 4. For mixed coordination you can also use the keywords “heterocoord”, “heterocoord 34” etc.
