Inputs

Name	Type & Properties	Description
--input	file required multiple	The input h5mu file(s)
--modality	string	The modality to use
--ingestion_method	string required	Method that was used to ingest the data - this will define the structure of the report that is generated.
--obs_sample_id	string	The key in the h5mu file that contains the sample ID. If not provided, each H5MU file will be considered as a separate sample.
--obs_total_counts	string	The key in the h5mu .obs field that contains the total counts.
--obs_num_nonzero_vars	string	The key in the h5mu .obs field that contains the number of nonzero vars.
--obs_fraction_mitochondrial	string	The key in the h5mu .obs field that contains the fraction mitochondrial genes.
--obs_fraction_ribosomal	string	The key in the h5mu .obs field that contains the fraction ribosomal genes.
