# SCMER - Manifold Preserving Feature Selection 
[![Documentation Status](https://readthedocs.org/projects/scmer/badge/?version=latest)](https://scmer.readthedocs.io/en/latest/?badge=latest) [![PyPI](https://img.shields.io/pypi/v/scmer?color=blue&logo=pypi)](https://pypi.org/project/scmer) ![PyPI - Downloads](https://img.shields.io/pypi/dm/scmer) [![Code Ocean](https://codeocean.com/codeocean-assets/badge/open-in-code-ocean.svg)](https://doi.org/10.24433/CO.6781338.v1)

SCMER is a feature selection methods designed for single-cell data analysis. 
It selects a compact sets of markers that preserve the manifold in the original data.
It can also be used for data integration by using features in one modality to match the manifold of another modality.

## Tutorials ##
Tutorials are available at https://scmer.readthedocs.io/en/latest/examples.html

You may start with the [Melanoma data (Tiorsh et al.)](https://scmer.readthedocs.io/en/latest/melanoma.html).

To install the latest version here, you can do
```
pip install git+https://github.com/KChen-lab/SCMER/
```

## Long Term Support ##
We try to keep the package work with new versions of Python and other dependencies. 
Lastest tested version: python 3.11 + torch 2.1.1 + SCANPY 1.9.6
OS: Windows 10.
Hardware: AMD Ryzen R5 3600 + Nvidia RTX 3080
For other tested version, please check the `lts` folder in this repository.
The four scripts in the folder can also give you an idea of how to run SCMER for a given scenario.

### Running in R ###
Python is more established in machine learning tasks, but many people prefer R as their primary language in data science. Luckily, a thin wrapper is what you need to run SCMER in R. Please see this short [tutorial](https://htmlpreview.github.io/?https://github.com/KChen-lab/SCMER/blob/master/notebooks/melanoma-gpu-with-batch-in-r.nb.html).

## Additional package info
Using GPU can be tricky sometimes. Here is a [list of package versions](https://github.com/KChen-lab/SCMER/blob/master/notebooks/package_versions.txt) we successfully used with GPU.
