• Input Data (T2ED output data) - The user User may click on "change input" button in order to use a data file among the ones that are already uploaded or created within his/her personal workspace. It is strongly recommended to use as input the output file created by “Transformation to Equivalent Dimensions” Application.
• Number of clusters – The User selects the number of cluster within which the entire data sample will be divided. The number must be an integer greater than 1.
• Clustering algorithm – The User may select between 2 clustering algorithms, namely “Partitioning” clustering (K-means algorithm) or “Hierarchical” algorithm (Ward’s method). Fuzzy clustering is not supported yet in IS-EPOS platform.
• Clustering method – The User may now select the method for the clustering tree generation, among “average”, “centroid”, “complete”, “median”, “single”, “ward” and “weighted” (this option is only available when “Hierachical” Clustering algorithm is selected).
• Number of leaf nodes – The User finally selects the number of leaves to be demonstrated the final Ward diagram. The number must be an integer greater than 1 and smaller than the total number of the data points (this option only is only available when “Hierachical” Clustering algorithm is selected).

After defining the aforementioned parameters, the user User shall click on the  ‘RUN’ button (green tab in Figure 4) and the calculations are performed. The Status changes from 'CREATED' through  'SENT_TO_SERVER', 'RUNNING' and finally 'FINISHED' and the output is created and plotted in the main window. The Analysis Results table appear on the screen and comprise the following outputs:
