  Active assay: SCT (22220 features, 3000 variable features)
   1 other assay present: RNA

  I want to plot TCRVδ2

  Error: None of the requested features were found: TCRVδ2 in slot data
  In addition: Warning message:

  This data base is about human TCR genes

  But I even can not find this gene here
  Do you know what is the corresponding symbol for this gene used in Seurat?
  
  user3631: TCRVδ2 is not a gene, but it defines a specific subset of gamma-delta TCRs. You can look at TRDC (delta chain) and TRGC1 and TRGC2 (gamma chains). TCRVδ2 should have the combo TRDC-TRGC1, while TCRVδ1 should express TRDC-TRGC2. You may need to increase the resolution of your clustering, to avoid clustering the gamma-delta T cells with the NK cells.
