center_2	boolean, to center each the feature in Modality 2 prior to computing latent dimensions
center_consensus	boolean, to center the combined set of latent dimensions (from both modalities)
normalize_row	boolean, to normalize each cell's latent vector after dimension-reduction for both modalities
normalize_singular_value	boolean, to normalize each modality by its largest singular value
recenter_1	boolean, to center each latent dimension in Modality 1 after computing latent dimensions
recenter_2	boolean, to center each latent dimension in Modality 2 after computing latent dimensions
recenter_consensus	boolean, to center the latent dimension after Consensus PCA
rescale_1	boolean, to rescale each latent dimension in Modality 1 after computing latent dimensions
rescale_2	boolean, to rescale each latent dimension in Modality 2 after computing latent dimensions

scale_1	boolean, to rescale each the feature in Modality 1 prior to computing latent dimensions
scale_2	boolean, to rescale each the feature in Modality 2 prior to computing latent dimensions
scale_consensus	boolean, to rescale the combined set of latent dimensions (from both modalities)
scale_max_1	numeric or NULL, to threshold Modality 1 in magnitude prior to computing latent dimensions

scale_max_consensus	numeric or NULL, to threshold the combined set of latent dimensions in magnitude prior to computing latent dimensions
svd_1	list of u, d, v for the SVD of Modality 1 if it's already computed
