+cellular information into spatial pixels to reduce resource requirements for
+spatial omics data analysis.  SEraster reduces the number of points in spatial
+omics datasets for downstream analysis through a process of rasterization where
+single cells gene expression or cell-type labels are aggregated into equally
+sized pixels based on a user-defined resolution.  SEraster can be incorporated
+with other packages to conduct downstream analyses for spatial omics datasets,
+such as detecting spatially variable genes.")
