I'm wanting to create a merged object in Seurat using 2 10x Visium 'slices'. However, when I create an object, Seurat assigns an identity "SeuratProject" to the objects (by default I'm guessing; see attached plot). This will be problematic when I attempt to merge the objects as there will be unintended duplicates of the objects.
Here's what I'm attempting to use to create the 10x Spatial Object:
brain1 <- Load10X_Spatial(data.dir = "~/xxx", filename = "filtered_feature_bc_matrix.h5", assay = "Spatial", slice = "slice1", filter.matrix = TRUE, to.upper = FALSE)
I'd need the ability to assign unique ident to each of these (and any subsequent) slices/data.
