What does CONVERT do ?
CONVERT is a utility program to conversion a
SIMIL-type similarity (S)
matrix into a distance (D) matrix, or vice versa.
This program has been written because most of the programs in R
require that the
SIMIL-type file provided as input be of the
similarity type. So, distance files must be converted in many
instances; when distances are larger than 1, the first type of
transformation produces negative "similarities"; notice that
despite of that, the programs that use these similarity files have been
built to handle the values correctly. The last forms of transformation
guarantees that all the similarities obtained after transformation are
in the [0, 1] interval.
