The stereoAlign python package is available on Pypi and can be installed through
pip install stereoAlignImport stereoAlign in python
import stereoAlignWe created the python package called stereoAlign that uses scanpy to streamline the integration of single-cell datasets and evaluate the results. The package contains several modules for preprocessing an anndata object, running integration methods and evaluating the resulting using a number of metrics. Functions for the data integration methods are in stereoAlign.alignment or for short stereoAlign.alg and metrics are under stereoAlign.metrics.
