This will determine how BioVinci calculates the distance between clusters. You can choose among Ward’s minimum variance, Complete linkage, Single linkage, UPGMA, and WPGMA. You are now ready to set parameters for your clustering. Step 2: Set up parameters for hierarchical clusteringĭrag your data (either the whole table or selected columns) to the Matrixplaceholder.
You can also edit the source table by clicking Edit data (top left). From here, you can drag the whole table, or select multiple columns to cluster. There is a Source list on the left that shows the data table and its columns that you’ve just imported. Or, type the name of the function in the search box. In the Analysis window, click Analysis, then select Hierarchical clustering. Once the file is uploaded, you will be prompted to name the workset.
Open BioVinci -> Create new work set -> Drag and Drop file here. Note that BioVinci always cluster by columns, so make sure they are set up correctly. This function automatically excludes all categorical columns. You just need to make sure that all numeric columns in the table are appropriate to calculate distances. It’s real easy!īioVinci supports TSV, CSV and Excels files. In this tutorial, we will show you how to perform hierarchical clustering and produce a heatmap with your data using BioVinci. You see them showing gene expression, phylogenetic distance, metabolomic profiles, and a whole lot more. They are an intuitive way to visualize information from complex data.
