SEACells 0.3.3

SEACells:

Single-cEll Aggregation for High Resolution Cell States

Installation and dependencies

1. SEACells has been implemented in Python3.8 can be installed via pip:

    $> pip install cmake
    $> pip install SEACells
   

   It can also be installed directly from source.

    $> git clone https://github.com/dpeerlab/SEACells.git
    $> cd SEACells
    $> python setup.py install
   

2. If you are using conda, you can use the environment.yaml to create a new environment and install SEACells.

conda env create -n seacells --file environment.yaml
conda activate seacells

3. You can also use pip to install the requirements

pip install -r requirements.txt

And then follow step (1)

4. MulticoreTSNE issues can be solved using

conda create --name seacells -c conda-forge -c bioconda cython python=3.8
conda activate seacells
pip install git+https://github.com/settylab/Palantir@removeTSNE
git clone https://github.com/dpeerlab/SEACells.git
cd SEACells 
python setup.py install

3. SEACells depends on a number of python3 packages available on pypi and these dependencies are listed in setup.py.

   All the dependencies will be automatically installed using the above commands

4. To uninstall:

    $> pip uninstall SEACells
   

Usage

1. ATAC preprocessing: notebooks/ArchR folder contains the preprocessing scripts and notebooks including peak calling using NFR fragments. See notebook here to get started. A version of ArchR that supports NFR peak calling is available here.

2. Computing SEACells: A tutorial on SEACells usage and results visualization for single cell data can be found in the [SEACell computation notebook] (https://github.com/dpeerlab/SEACells/blob/main/notebooks/SEACell_computation.ipynb).

3. Gene regulatory toolkit: Peak gene correlations, gene scores and gene accessibility scores can be computed using the [ATAC analysis notebook] (https://github.com/dpeerlab/SEACells/blob/main/notebooks/SEACell_ATAC_analysis.ipynb).

4. TF activity inference: TF activities along differenitation trajectories can be computed using the [TF activity notebook] (https://github.com/dpeerlab/SEACells/blob/main/notebooks/SEACell_tf_activity.ipynb).

5. Large-scale data integration using SEACells : Details are avaiable in the [COVID integration notebook] (https://github.com/dpeerlab/SEACells/blob/main/notebooks/SEACell_COVID_integration.ipynb)

6. Cross-modality integration : Integration between scRNA and scATAC can be performed following the Integration notebook
