Preprocessing

preprocessing.centered_pca(adata[, n_comps, ...])	Performs PCA on the centered data matrix and stores the results in obsm.
preprocessing.project_pca(query_adata[, ...])	Projects the query data to the principal components of the reference data.
preprocessing.reconstruct_pca(query_adata[, ...])	Performs PCA on the data matrix and projects the data to the principal components.
preprocessing.annotate_compounds(adata, ...)	Annotates compounds in adata using pertpy and PubChem.
preprocessing.encode_onehot(adata, ...[, ...])	Encodes covariates obs as one-hot vectors and stores them in uns.
preprocessing.get_molecular_fingerprints(...)	Computes Morgan fingerprints for compounds in adata and stores them in uns.
preprocessing.compute_wknn([ref_adata, ...])	Compute the weighted k-nearest neighbors graph between the reference and query datasets
preprocessing.transfer_labels(query_adata, ...)	Transfer labels from the reference to the query dataset.
