Getting started with UNAGI:
calculate the distance between two stages and connect the clusters in two stages with smallest distance with midpath in iterative training
midpath (str) – The task name
iteration (int) – The iteration of the training
stage1 (anndata) – The data of the first selected stage
stage2 (anndata) – The data of the second selected stage
cutoff (float) – The cutoff of p-value
edges (list) – The edges between two stages
