One liner tool to check the quality of your single-cell atlases
Project description
CheckAtlas
CheckAtlas is a one liner tool to check the quality of your single-cell atlases. For every atlas, it produces the quality control tables and figures which can be then processed by multiqc. CheckAtlas is able to load Scanpy, Seurat, and CellRanger files.
Summary
-
Parse Scanpy, Seurat and CellRanger objects
CheckAtlas should be able to load : .rds, .h5 and .h5ad corresponding to single-cell experiment. Need to implement :
- automatic conversion of Seurat object to Scanpy with SeuratDisk
- Rapid check-up of files to see if a Seurat or Scanpy can be found
- Automatic search in Scanpy files of key information = raw data, normalized data, integrated data, reductions, layers, assays, metadatas, etc...
-
Create checkatlas summary files
Go through all Scanpy files and extract summary information. We won't to extract :
- All basic QC (nRNA, nFeature, ratio_mito)
- General information (nbcells, nbgenes, nblayers)
- All elements in scanpy objects (obs, obsm, uns, var, varm)
- Reductions (pca, umap, tsne)
- All metrics (clustering, annotation, dimreduction, specificity)
-
Parse checkatlas files in MultiQC
Update MultiQC project to add checkatlas parsing. Dev project in: https://github.com/becavin-lab/MultiQC/tree/checkatlas

Examples
- Evaluate and compare different atlases: https://github.com/becavin-lab/checkatlas/blob/3a4f88e94716c09a3b9c86010f570743a5855461/examples/Atlas_comparison.ipynb

- Evaluate different version of your atlas: https://github.com/becavin-lab/checkatlas/blob/3a4f88e94716c09a3b9c86010f570743a5855461/examples/Version_comparison.ipynb

Installation
CheckAtlas can be downloaded from PyPI. However, the project is in an early development phase. We strongly recommend to use the developmental version.
Install checkatlas development version
git clone git@github.com:becavin-lab/checkatlas.git
pip install checkatlas/.
Install MultiQC with checkatlas file management. This version of MultiQC is available at checkatlas branch of github.com:becavin-lab/MultiQC.
git clone git@github.com:becavin-lab/MultiQC.git
cd MultiQC/
git checkout checkatlas
pip install .
Install it from PyPI
pip install checkatlas
Usage
The one liner way to run checkatlas is the following:
$ cd your_search_folder/
$ python -m checkatlas .
#or
$ checkatlas .
Or run it inside your python workflow.
from checkatlas import checkatlas
checkatlas.run(path, atlas_list, multithread, n_cpus)
