No cell overlap between new meta data and Seurat object

[handesome]

Hi! Thank you for developing the package!when I download human_myeloid_seurat_obj.rds and run the vignette data_S$celltype <- cluster_relabel[as.character(data_S$cluster)] error: No cell overlap between new meta data and Seurat object so how to solve the problem?Thanks!!

Hi, if you are using Seurat v5, you can try to update the object by

library(SeuratObject)
data_S = SeuratObject::UpdateSeuratObject(data_S)

Then, change the following line in the first code block to

data_S@meta.data$celltype <- cluster_relabel[as.character(data_S$cluster)]

Hope this can solve the issue.
