Hi!
I would convert the simmilarities into dissimilarities by myself.
Its quite easy.
For example to make a dissimilarity from correlation which is a simmilarity measures you can:
dcorr = 1 - cor
and dcorr will be a dissimilarity.
More general. Make the smallest value the largest and the largest the smallest. And ensure that the transformation is monotonical.
Sincerely
Eryk
