Description: SEraster is a rasterization preprocessing framework that
        aggregates cellular information into spatial pixels to reduce
        resource requirements for spatial omics data analysis. 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. SEraster is built on an R/Bioconductor S4 class
        called SpatialExperiment. SEraster can be incorporated with
        other packages to conduct downstream analyses for spatial omics
        datasets, such as detecting spatially variable genes.
