 The MuData object required should contain normalised data in the X slot of each modality,  a 'raw_counts' layer in each modality, and a sample_id column in each slot of the obs and the outer obs. A plus is a PCA in the obsm slot for each modality, if not it will be calculated on the flight with default parameters.
