Hello, I integrated 12 samples that have following Seurats integration protocol here. These samples where each hashed based on their stimulation condition (two protein stimulations and one unstimulated). When I run

DimPlot(Data_group1, reduction = "umap", cols=pal, group.by = "hash.ID")

I get back a umap that shows the different tags. My issue is that I have Sample_1_unstim, Sample_2_unstim or I get Protein_1_stim, protein_1, etc. I want just want it to say Unstim or Protein_1_stim but I do not know how to change this in the metadata. Does anyone have any ideas? Thanks!
