You signed out in another tab or window. Navigation Menu Toggle navigation. It would be useful to be able either specify matrix/genes/barcodes Hello, I am trying to use a scanpy object as a reference, to annotate my query object which is processed in seurat. , pd. , 'ann1' or ['ann1', 'ann2']. The ingest function assumes an annotated reference dataset that captures the biological variability of interest. You may also undertake your own preprocessing, simulate doublets with scrublet_simulate_doublets() , and run the core scrublet function scrublet() with adata_sim set. reticulate-free single cell format conversion Resources.
