 `SEraster` is a rasterization preprocessing framework that aggregates cellular information into spatial pixels to reduce resource requirements for spatial omics data analysis. This is the `SEraster` R documentation website. Questions, suggestions, or problems should be submitted as [GitHub issues](https://github.com/JEFworks-Lab/SEraster/issues).
