Error in detect_tissue: setting an array element with a sequence

[QuinceyLv]

Hi, Thanks for the great package. I was running spacemake with visium data, and got an exception:

rule run_automated_analysis: input: projects/visium_demo/processed_data/DSG_Control/illumina/complete_data/dge/dge.exon.polyA_adapter_trimmed.mm_included.spatial_beads_visium.h5ad output: projects/visium_demo/processed_data/DSG_Control/illumina/complete_data/automated_analysis/visium/umi_cutoff_1000/DSG_Control_visium_results.h5ad jobid: 47 wildcards: project_id=visium_demo, sample_id=DSG_Control, data_root_type=complete_data, downsampling_percentage=, run_mode=visium, umi_cutoff=1000, puck_barcode_file_id_qc=visium

The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (39,) + inhomogeneous part.

Then I checked the code in spacemake.spatial.utils.detect_tissue: https://github.com/rajewsky-lab/spacemake/blob/9ce7d8905a8402f2115ec22ea7890fa64b81fe84/spacemake/spatial/util.py#L139

ChatGPT says this should be:

islands_array = np.array(islands, dtype=object)
max_index = np.argmax(island_sizes)
tissue_islands = np.delete(islands_array, max_index)
tissue_islands = tissue_islands.tolist()

I'm using spacemake 0.7.9 with numpy 1.26.4. Is that correct? Thanks in advance.
