• Click the Merged counts data node
• Click Exploratory analysis in the toolbox
• Click Graph-based clustering 
• Click Gene Expression for Include features where "Feature type" is
• Click Configure to access the advanced settings
• Set Number of principal components to 15

Once Graph-based clustering has finished running and produced a Clustering result data node, we can visualize the results using UMAP or t-SNE.  

...

Both are dimensional reduction techniques that group cells with similar expression into visible clusters. 

• Click the Clustering result data node 
• Click Exploratory analysis in the toolbox
• Click UMAP
• Click Gene Expression for Include features where "Feature type" is
• Click Configure to access the advanced settings
• Set Number of principal components to 15
• Click Apply 
  
• Click Finish to run (Figure 18)
  
  

The Analyses tab now includes a UMAP task node (Figure 18).

• Double-click the UMAP task node to open the task report

The UMAP task report includes a scatter plot with the clustering results coloring the points (Figure 19).
