-//This tool can be used if you have a big unlabeled dataset and you need to group all information into smaller categories or clusters. A number of clusters (k-centroids) needs to be defined for running the tool. It's an iterative process where each cluster is associated with a centroid. In the calculative process the sum of distances minimizes between the datapoints and their corresponding clusters. The tool will assign each datapoint to its closest k-centered centroid and a cluster is created hence each cluster will have commonalitites away from other clusters. // +//This tool can be used if you have a big 1D geophysical model dataset and you need to group all information into categories/clusters. The calculation is iterative where the sum of distances is minimized between datapoints and their corresponding centroid that later forms the basis of the clusters. The number of clusters need to be predefined to make the calculation where each datapoints continually will be assigned to its closest centroid. In this case the closest centroid may consist of commonalities away from other clusters. //

-Alt om Cluster Wizard. The cluster calculation can now be run within layers and region. Furthermore, the output cluster points are shown on the top plot as default.+
