Is that there is way that I can import gene list into Seurat to define cell type? Since the default cell types in Seurat is not enough for our research. For example, we want to mark a subtype of B cells in Seurat, but seems like Seurat only have general B cell, I'm planning to download gene list from Genomic Cytometry, and then import the gene list into Seurat and then Seurat define cell types in the cluster based on the gene list I import. Do Seurat support this function?
