+The new umap shows new structure. If we select the rather densely populated area on the left, we have identified the cluster that exclusively represents the toxin cluster. To select the ribosome cluster, we lasso the tip of the larger and fuzzier area by holding :kbd:`Shift` while outlining the area.
