+- Conversion of the following data: images, cell boundaries (polygons or spot), transcripts, cell-by-gene table, and cell categories (or observations).
 - Image alignment can be made on the Xenium Explorer, and then the `SpatialData` object can be updated
 - When working on the `SpatialData` or `AnnData` object, new cell categories can be easily and quickly added to the Explorer
 - When selecting cells with the "lasso tool" on the Explorer, it's easy to select back these cells on the `SpatialData` or `AnnData` object
