Thank you. I have managed to get the cluster output. My questions seem trivial. I am bit new to Perl.

I was wondering if there is any module to represent the cluster output into dendrogram. I checked the search.CPAN to find if there are any modules for graphical representation of the cluster . But I could not find any. They are all for Bioclusters.

I need to represent the result in graphical form. Since there is a module to obtain the clustering result,is there any module to represent this result in graphical(dendrogram) format?

($result, $linkdist) = Algorithm::Cluster::treecluster(%param);
