gsc :: Fractional d => Dendrogram d a -> Dendrogram d (a, d)Source

*O(n^2)* Calculates the Gerstein/Sonnhammer/Chothia
weights for all elements of a dendrogram. Weights are
annotated to the leafs of the dendrogram while distances in
branches are kept unchanged.

Distances `d`

in branches should be non-increasing and between
`0`

(in the leafs) and `1`

. The final weights are normalized
to average to `1`

(i.e. sum to the number of sequences, the
same they would sum if all weights were `1`

).
