motionmapperpy : Modified Python 3.0 implementation of MotionMapper

This package is a GPU accelerated implementation of the MotionMapper pipeline for creating low dimensional density maps using tSNE or UMAP. Some methodologies may differ from the original implementation, please refer to the source code for a detailed look.

Package functions are:

  • Subsampling training points by running mini-tSNEs on a group of datasets.
  • Re-embedding new points on a learned tSNE map.
  • Watershed segmentation and grouping.

Installation:

  1. (OPTIONAL) Create a new conda environment conda create -n mmenv python=3.6
  2. Activate desired conda environemnt conda activate mmenv
  3. Download the repository and unzip contents. Open terminal and navigate to unzipped folder containing setup.py.
  4. Run
pip install -U h5py==2.1 
pip install numpy scikit-image hdf5storage
python setup.py install

Additionally, install cupy (if GPU present on system) by following the instructions here.
