 `SEraster` reduces the number of spatial 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`. Here, we refer to a particular `resolution` of rasterization by the side length of the pixel such that finer `resolution` indicates smaller pixel size and coarser `resolution` indicates larger pixel size.
