Description

Performs totalVI integration by mapping the query dataset to a reference dataset or model.

Inputs

Name	Type & Properties	Description
--input -i	file required	Input h5mu file with query data to integrate with reference.
--reference -r	file required	Input h5mu file with reference data to train the TOTALVI model.
--force_retrain -f	boolean_true	If true, retrain the model and save it to reference_model_path
--query_modality	string
--query_proteins_modality	string	Name of the modality in the input (query) h5mu file containing protein data
--reference_modality	string
--reference_proteins_modality	string	Name of the modality containing proteins in the reference
--input_layer	string	Input layer to use. If None, X is used
--obs_batch	string	Column name discriminating between your batches.
--obs_size_factor	string	Key in adata.obs for size factor information. Instead of using library size as a size factor, the provided size factor column will be used as offset in the mean of the likelihood. Assumed to be on linear scale.
--obs_categorical_covariate	string multiple	Keys in adata.obs that correspond to categorical data. These covariates can be added in addition to the batch covariate and are also treated as nuisance factors (i.e., the model tries to minimize their effects on the latent space). Thus, these should not be used for biologically-relevant factors that you do _not_ want to correct for.
--obs_continuous_covariate	string multiple	Keys in adata.obs that correspond to continuous data. These covariates can be added in addition to the batch covariate and are also treated as nuisance factors (i.e., the model tries to minimize their effects on the latent space). Thus, these should not be used for biologically-relevant factors that you do _not_ want to correct for.
--var_input	string	.var column containing highly variable genes. By default, do not subset genes.
