Simply select the new method of hierarchical cluster analysis you want to use from the pull-down list and your proximity matrix will be clustered by the new method.  Note the choice of 11 standard methods - more than most packages allow - for the full list, see hierarchical cluster analysis.  Note also that exemplars have been computed, and 1 tied proximity was detected - see exemplars for details.  Unlike many other clustering packages, ClustanGraphics can test the sensitivity of the resulting clusters to tied proximities.
