I have downloaded JCem for Java, and I do have the license for JKlustor.
Could someone tell me if there is a way to run JKlustor in graphical mode (with GUI, like LibraryMCS) or I it is command line based application?
JKlustor is a comman-line base application. Alternatively, you can try this web application that provides some clustering methods. It plays demo purposes but provides a simple gui that may help.
Many thanks for your prompt response with helpful explanations. Now I know that I am not missing JKlustor GUI since it does not exist.
Btw, which clustering algorithm do you intend to use in JKlustor?
Those that are available in the web application (see my previous post) provide more modern (though not state-of-the-art) approaches like k-means and sphere exclusion than the command line tools.
