Description

Generation of cell embeddings for the integration of single cell transcriptomic count data using scGPT.

Inputs

Name	Type & Properties	Description
--input	file required	The input h5mu file containing tokenized gene and count data.
--modality	string	Which modality from the input MuData file to process.
--model	file required	Path to scGPT model file.
--model_vocab	file required	Path to scGPT model vocabulary file.
--model_config	file required	Path to scGPT model config file.
--obsm_gene_tokens	string	The key of the .obsm array containing the gene token ids
--obsm_tokenized_values	string	The key of the .obsm array containing the count values of the tokenized genes
--obsm_padding_mask	string	The key of the .obsm array containing the padding mask.
--var_gene_names	string	The name of the .var column containing gene names. When no gene_name_layer is provided, the .var index will be used.
--obs_batch_label	string	The name of the adata.obs column containing the batch labels. Must be provided when 'dsbn' is set to True.
--finetuned_checkpoints_key	string	Key in the model file containing the pretrained checkpoints. Only relevant for fine-tuned models.
