 +The K-Means button is found on the toolbar and under {{:sift_outlier_detection.png?30}}**Outlier Detection**.
 +
 +  * **Number of Clusters**: The number of clusters to be calculated.
 +  * **Maximum iterations**: How many times the calculations will be run, more iterations will refine the results at the cost of longer processing times.
 +  * **Determine Number of PCs Using Variance Explained**: Can be used to determine the number of PCs (i.e. dimensionality) of the K-Means test using variance explained instead of number of PCs
 +  * **Number of PCs (1-25)**: The number of principal components representing the workspace.
 +  * **Scale PC Scores to Variance Explained**: Normalizes the scale on the workspace scores using the variance explained.
 +  * **Switch Display Style to by Cluster**: Automatically changes the display style to cluster, after running a K-Means Test.
 +  * **Use Custom Seed For First Centroid**: Allows the selection of a custom seed instead of a randomly generated one, creates consistent results across runs.
