Show the distribution of CDR3 region lengths.
`

Show the distribution of CDR3 region lengths.

Ignores NaN values.

Parameters:

  • adata (Union[AnnData, MuData, DataHandler]) – AnnData or MuData object that contains AIRR information.

  • chain (Union[Literal['VJ_1', 'VJ_2', 'VDJ_1', 'VDJ_2'], Sequence[Literal['VJ_1', 'VJ_2', 'VDJ_1', 'VDJ_2']]] (default: 'VJ_1')) – One or multiple chains to include in the plot.

  • color (str) – Color by this column from obs. E.g. sample or diagnosis

  • cdr3_col (str (default: 'junction_aa')) – AIRR rearrangement column from which sequences are obtained

  • combine_fun (Callable (default: <function sum at 0x7fe3ccdbcff0>)) – A function definining how the cdr3_col columns should be merged, in case multiple ones were specified. (e.g. sum, mean, median, etc).

  • normalize (Union[str, bool, None] (default: None)) – If True, compute fractions of abundances relative to the cdr3_col column rather than reporting abosolute numbers. Alternatively, the name of a column containing a categorical variable can be provided according to which the values will be normalized.

  • viztype (Literal['bar', 'line', 'curve'] (default: 'bar')) – Type of plot to produce.

  • airr_mod (default: 'airr') – Name of the modality with AIRR information is stored in the MuData object. if an AnnData object is passed to the function, this parameter is ignored.

  • airr_key (default: 'airr') – Key under which the AIRR information is stored in adata.obsm as an awkward array.

  • chain_idx_key (default: 'chain_indices') – Key under which the chain indices are stored in adata.obsm. If chain indices are not present, index_chains() is run with default parameters.

  • **kwargs – Additional parameters passed to the base plotting function

Return type:

Union[list[Axes], AnnData]

Returns:

Axes object
