Neighbour calculation

Name	Type & Properties	Description

Clustering options

Name	Type & Properties	Description
--obs_cluster	string	Prefix for the .obs keys under which to add the cluster labels. Newly created columns in .obs will be created from the specified value for '--obs_cluster' suffixed with an underscore and one of the resolutions resolutions specified in '--leiden_resolution'.
--leiden_resolution	double multiple	Control the coarseness of the clustering. Higher values lead to more clusters.
