Description

I ran xenium() with default parameters on official data from 10x Genomics (such as https://www.10xgenomics.com/datasets/ffpe-human-breast-with-custom-add-on-panel-1-standard).

However, I noticed that when I plotted the H&E image using the spatialdata-plot package, there were some missing tiles, as shown in the following image:

Image

The missing tiles are always the same if I run xenium() multiple times, so it doesn't look like a random drop.

I checked the original .ome.tif image in QuPath and there are no missing tiles.

Packages version:

  • spatialdata = 0.2.5
  • spatialdata-io = 0.1.5
  • spatialdata-plot = 0.2.7

Research direction

Reproduce the issue by running xenium() with default parameters on the linked 10x Genomics dataset, then plot its H&E image with spatialdata-plot. Compare the result with the original .ome.tif in QuPath and investigate why the same tiles are missing; done means the plotted image contains all source tiles.
