What happened?

I'm trying to read in visium data with antibody capture data but for some reason the antibody capture data is not registering. Is there something I'm doing wrong? I couldn't find documentation on how to do this. Although I do see the antibody capture data in the web_summary.html

However read_10x_mtx method works directly on the folder, is there a way to add gex_only functionality to the read_visium function?

Minimal code sample

print(key)
        adata = sc.read_visium(path, count_file='filtered_feature_bc_matrix.h5', load_images=True, )
        print(adata)

        # Separate RNA and protein data
        rna_data = adata[:, adata.var['feature_types'] == 'Gene Expression']
        protein_data = adata[:, adata.var['feature_types'] == 'Antibody Capture']

        # Verify the separated data
        print("RNA data shape:", rna_data.shape)
        print("Protein data shape:", protein_data.shape)

Error output

Hi, I just wanted to follow up on this.

Hi, I don’t have much experience with that data. Does squidpy work better? https://squidpy.readthedocs.io/en/stable/api/squidpy.read.visium.html

scanpy doesn’t have much support for spatial analysis, squidpy is built for it.

Hi, let me give that a shot.

Hi, I tried that and got this error. I think it's because it's recognizing both antibody data and gene data and throwing an error.
