Neighbor embedding spectrum for single-cell data

This repository contains scripts and notebooks to reproduce the experiments in Visualizing single-cell data with the neighbor embedding spectrum (bioarxiv)

It depends on the ne-spectrum package, which computes neighbor embedding spectra.

Higher attraction improves the global structure as measured by Spearman distance correlation. Higher repulsion improves local structure as measured by kNN recall.

Installation

Create and activate the conda environment

conda env create -f environment.yml
conda activate ne_spectrum_scRNAseq

Install the utilities for this repository

python setup.py install

Usage

To reproduce the data for the figures in the main paper, run

python scripts/compute_embds.py --spectrum_via tsne
python scripts/compute_metrics.py --spectrum_via tsne

To reproduce the data for the figures in the supplementary, run

python scripts/compute_embds.py --spectrum_via cne
python scripts/compute_metrics.py --spectrum_via cne

Then run the notebooks in notebooks/ to generate the figures and the videos.
