I have used DNACLUST to cluster short sequences of DNA. I have all clusters in separate fasta files. I need to visualize the clusters, preferably in neighboring histograms or another commonly used cluster graph output (like what is commonly seen with k-mer "clouds"). The goal is to progressively relax the stringency threshold for making clusters and then to SEE how closely related the clusters are with each threshold. This visualization will help me (and my boss) to determine how the distance between clusters behave as the similarity threshold is progressively relaxed. I am not looking for a program that will cluster the DNA sequences and then visualize the data. I have already clustered the sequences and don't want to reinvent the wheel. Thanks.
