If a single cell data node contains cell attribute information, e.g., clustering results, classifications, or imported attributes, a counts-type data node containing the number of cells from each attribute group for each sample can be generated and used for downstream analysis. 

To invoke Generate group cell counts: 

• Click a single cell count data node with cell-level attribute information
• Click Pre-analysis tools in the toolbox
• Click Generate group cell counts 
• Select the attribute to group the cells from the Group by drop-down menu (Figure 1)
• Click Finish  
  
  

A group cell counts node will be generated. The data node contains a matrix of cell counts in each sample for each group. You can view the counts results in the Group cell counts report (Figure 2).

The Cell counts data node is a counts type data node and downstream analysis tasks, such as normalization, PCA, and ANOVA, can be used to analyze the group cell counts data.
