This function checks that the Seurat object contains all the
necessary metadata for functions in scFeatures.
For scRNA-seq, it must contain sample and celltype.
For spatial proteomics, it must contain sample, celltype and
and spatial proteomics data, it must contain sample and x_cord
and y_cord.
For spatial transcriptomics data, it must contain sample, x_cord
y_cord and a predictions assay.
check_data(data, type = "scrna")A Seurat object containing expression.
Type of dataset, either "scrna" (for scRNA-seq), "spatial_t" (for spatial transcriptomics) or "spatial_p" (for spatial proteomics).
