NettetWhen iteratively running a clustering algorithm, the labels given to clusters by the clustering algorithm depend on cluster size. With Leiden, the biggest cluster will be named "0", the second biggest will be named "1", and so on. In order to make cluster labels equivalent across iterations, a relabeling step is run within the scallop pipeline.
