ClusterSnnGraphLeidenResults

Wrapper around the SNN Leiden clustering results on the Wasm heap, produced by clusterSnnGraph.

Classes

ClusterSnnGraphLeidenResults

Methods

free()

Source:

clusterSnnGraph.js, line 401

Returns:

Frees the memory allocated on the Wasm heap for this object. This invalidates this object and all references to it.

membership(optionsopt) → (nullable) {Int32Array|Int32WasmArray}

Source:

clusterSnnGraph.js, line 387

Parameters:

Name Type Attributes Default Description

options

object

{}

Optional parameters.

Properties

Name	Type	Attributes	Default	Description
`copy`	boolean \| string	<optional>	`true`	Whether to copy the results from the Wasm heap, see `possibleCopy`.
`fillable`	boolean	<optional>	`false`	Whether to return a fillable array, to write to this object. If `true`, this method automatically sets `copy = false` if `copy` was previously true. If `false` and the array was not previously filled, `null` is returned.

Returns:

Array containing the cluster membership for each cell. Alternatively null, if fillable = false and the array was not already filled.

Type: Int32Array | Int32WasmArray

modularity() → (nullable) {number}

Source:

clusterSnnGraph.js, line 356

Returns:

The quality of the Leiden clustering. Alternatively null, if this has not been set by setModularity.

Note that Leiden's quality score is technically a different measure from modularity. Nonetheless, we use modularity for consistency with the other SNN clustering result classes.

Type: number

setModularity(modularity)

Source:

clusterSnnGraph.js, line 369

Parameters:

Name	Type	Description
`modularity`	number	Modularity value.

Returns:

Modularity value is set in this object. This is typically used after calling emptyClusterSnnGraphResults.
