Hi there, it's me again. I was running into the following error while trying to process some VISIUM HD data with the pipeline. Looks like the default settings can't necessarily detect images for VISIUM HD properly?

Command error:
  10:45PM INF instance metadata ami-id=ami-047eeab72a1800334 instance-id=i-01546edf255ede790 instance-type=r6id.4xlarge
  [WARN  tini (38)] Tini is not running as PID 1 and isn't registered as a child subreaper.
  Zombie processes will not be re-parented to Tini, so zombie reaping won't work.
  To fix the problem, use the -s option or set the environment variable TINI_SUBREAPER to register Tini as a child subreaper, or run Tini as PID 1.

Strange error, it seems like it does recognize the data as VisiumHD, but fails to load the png image

tissue_hires_image.png

. It claims that adding the imageio[pyav] or imageio[opencv] pip package could fix it. Could you share the png file in

Visium_HD_Human_Colon_Normal_P5/binned_outputs/square_002um/spatial/tissue_hires_image.png

so that I can check the problem?
