title: Where to find a reliable K-medoid(Not k-means) open source software/tool?
body: <p>I am learning the K-medoids algorithm so I am sorry if I ask inappropriate questions. As I know,the K-medoids algorithm implements a K-means clustering but use actual data points to be centroid instead of mathematical calculated means.</p>
  
  <p>As I googled online, I found a lot of k-means tools such as GenePattern, geWengh,...etc but not the k-medoids ones. Some nice friends has showed me that at Matlab, there is also one written by some user. However, I am afraid that personal implemented tool may still have some bugs or limitations. Thus, I am wondering if there is some widely used reliable open source software/tools  which uses actual data points as centroids to cluster. I need to find out the information about actual centroids so only returning clustering results is not enough. I prefer website online ones but if this is not the case, I am ok to install it to my local machine. Thank you very much,</p>
