labels_transfer/cellmapper

Description

Transfer labels from a reference to a query using CellMapper in a shared
embedding space.

Input dataset (query) arguments

Name	Type & Properties	Description
--input	file required	The query data to transfer the labels to. Should be a .h5mu file.
--modality	string	Which modality to use.
--input_obsm_features	string	The `.obsm` key of the embedding to use for the classifier's inference. If not provided, the `.X` slot will be used instead. Make sure that embedding was obtained in the same way as the reference embedding (e.g. by the same model or preprocessing).

Reference dataset arguments

Name	Type & Properties	Description
--reference	file	The reference data to train classifiers on.
--reference_obsm_features	string	The `.obsm` key of the embedding to use for the classifier's training. If not provided, the `.X` slot will be used instead. Make sure that embedding was obtained in the same way as the query embedding (e.g. by the same model or preprocessing).
--reference_obs_targets	string multiple	The `.obs` key(s) of the target labels to transfer.

Outputs

Name	Type & Properties	Description
--output	file required output	The query data in .h5mu format with predicted labels transferred from the reference.
--output_obs_predictions	string multiple	In which `.obs` slots to store the predicted information. If provided, must have the same length as `--reference_obs_targets`. If empty, will default to the `reference_obs_targets` combined with the `"_pred"` suffix.
--output_obs_probability	string multiple	In which `.obs` slots to store the probability of the predictions. If provided, must have the same length as `--reference_obs_targets`. If empty, will default to the `reference_obs_targets` combined with the `"_probability"` suffix.
--output_compression	string	Compression format to use for the output AnnData and/or Mudata H5 files. By default no compression is applied.
