text: user3171: I have followed the Seurat Tutorial:Integrating stimulated vs. control PBMC datasets to learn cell-type specific responses by using my data. And I am confused about how to write the script to calculate the cell number of each sample on each cluster. 
  I have run TSENPlot to know the samples and I'm using another TSENPlot to get the clusters. If I want to know find the cluster1 of each sample's number how can I write the script? 
  
  
  user383: Assuming you are following the basic seurat guide:
  pbmc@ident
  
  You can access the 'ident' slot of your Seurat object and you will get a vector of the cluster IDs and the names will be the respective cells.
  head(seuratobj@ident)
  Cell1A7 Cell1C4 Cell1D1 Cell1D2 Cell1D3 Cell1D5
  0 3 3 1 3 1 
  Levels: 0 1 2 3 4
