Input File ---------- First line: An integer showing the number (N) of entities you are clustering. Lines 2 to N+1: Labels for the entities. These should be strings, without spaces. Following N*(N-1)/2 lines: The upper diagonal matrix (free format). For example, see file test.dis. 7 First Second Third Fourth Fifth Sixth Seventh 100.0 100.0 50.0 33.0 25.0 20.0 100.0 50.0 50.0 33.0 33.0 100.0 33.0 20.0 25.0 33.0 20.0 25.0 100.0 100.0 100.0 By upper diagonal, I mean that the numbers are the similarities (or distances) from comparison of entity 1 v 2, 1 v 3, 1 v 4, 1 v 5, 1 v 6, 1 v 7, 2 v 3, 2 v 4, 2 v 5, 2 v 6, 2 v 7, 3 v 4, 3 v 5, 3 v 6, 3 v 7, 4 v 5, 4 v 6, 4 v 7, 5 v 6, 5 v 7, 6 v 7. In that order.
