# The Single Cell Tool Kit [![BioC-check](https://github.com/compbiomed/singleCellTK/actions/workflows/BioC-check.yaml/badge.svg?branch=master)](https://github.com/compbiomed/singleCellTK/actions/workflows/BioC-check.yaml) [![R-CMD-check](https://github.com/compbiomed/singleCellTK/actions/workflows/R-CMD-check.yaml/badge.svg?branch=master)](https://github.com/compbiomed/singleCellTK/actions/workflows/R-CMD-check.yaml) [![codecov](https://codecov.io/gh/compbiomed/singleCellTK/branch/devel/graph/badge.svg)](https://codecov.io/gh/compbiomed/singleCellTK) The Single Cell Toolkit (SCTK) in the *singleCellTK* R package is an analysis platform that provides an **R interface to several popular single-cell RNA-sequencing (scRNAseq) data preprocessing, quality control, analysis, and visualization tools**. SCTK imports raw or filtered counts from various scRNAseq preprocessing tools such as 10x CellRanger, BUStools, Optimus, STARSolo, and more. By integrating several publicly available tools written in R or Python, SCTK can be used to perform extensive quality control including doublet detection, ambient RNA removal. SCTK integrates analysis workflows from popular tools such as Seurat and Bioconductor/OSCA into a single unified framework. Results from various workflows can be summarized and easily shared using comprehensive HTML reports. Lastly, data can be exported to Seurat or AnnData object to allow for seamless integration with other downstream analysis workflows. ![](images/image-516723231.png) ## Features SCTK offers multiple ways to analyze your scRNAseq data through the R console, the command line, and a graphical user interface (GUI) with the ability to use a large number of algorithms from both R & Python integrated within the toolkit. - **Interactive Analysis:** The Shiny APP allows users without programming experience to easily analyze their scRNAseq data with a GUI. Try it out at <https://sctk.bu.edu/>. - **Console Analysis:** Traditional analysis of scRNAseq data can be performed in the R console using wrapper functions for a multitude of tools and algorithms. - **Reports:** Comprehensive HTML reports developed with RMarkdown allows users to document, explore, and share their analyses. - **Interoperability:** Tools from both R and Python package can be seamlessly integrated within the same analysis workflow without the need for manual conversion between different data objects and file formats. - **Number of tools:** SCTK provides access to the largest number of tools within the same platform streamlining end-to-end analysis workflows. Curated workflows include those from Seurat, Scanpy, Scater/Scran (Bioconductor), and Celda. ## Tutorials #### The Import and QC workflows allow users to import data from multiple formats and perform comprehensive quality control and filtering: [![](images/image-2029858439.png)](https://camplab.net/sctk/current/articles/import_data.html) #### The "A la carte" workflow lets users choose from a variety of options during each step of the clustering workflow including normalization, batch correction (optional), dimensionality reduction, 2-D embedding, and clustering: [![](images/image-295296270.png)](https://camplab.net/sctk/current/articles/02_a_la_carte_workflow.html) <https://camplab.net/sctk/current/articles/02_a_la_carte_workflow.html> #### The curated Seurat workflow recapitulates the steps for clustering and integration from the Seurat package: <https://camplab.net/sctk/current/articles/seurat_curated_workflow.html> #### The curated Celda workflow performs matrix factorization and clusters genes into co-expression modules: <https://camplab.net/sctk/current/articles/celda_curated_workflow.html> ## Installation R package `singleCellTK` is available on [Bioconductor](https://bioconductor.org/packages/release/bioc/html/singleCellTK.html) and can be installed with the following commands: ``` r if (!require("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install("singleCellTK") ``` Additional information on how to install from GitHub, install Python dependencies, and for troubleshooting is available on the [Installation](https://camplab.net/sctk/current/articles/installation.html) page. ## Citation If you use SCTK, please cite our *Nature Communication* paper > Rui Hong, Yusuke Koga, Shruthi Bandyadka, Anastasia Leshchyk, Yichen Wang, Vidya Akavoor, Xinyun Cao, Irzam Sarfraz, Zhe Wang, Salam Alabdullatif, Frederick Jansen, Masanao Yajima, W.
