Hello，everyone，how can I combine several AnnDataSets into one AnnDataSet? also,I don't quite understand, when I read a dataset, how do I get each object in it? I am a green hand, I don't understand many places, thank you very much!

AnnDataSet provide concatenated view of multiple AnnData objects. You can't combine AnnDataSet objects. AnnDataSet stores links to AnnData objects (h5ad files). To combine several AnnDataSet objects, you can recreate a new AnnDataSet using component h5ad files. To access individual AnnData object, you just need to open the relevant file using snap.read directly.
