Single Cell Trancriptomics

A personal collection focused on scRNA-seq analysis =)

Significance

scRNA-seq has emerged as a standard technology to study and enhance the understanding of transcription. The space here is dedicated to collect papers, methods, tutorials, and stuff related to the technology. It has been manually curated and content checked since 2020 April.

Welcome to single cell world

Getting started: scRNA-seq analysis 101

Advanced analysis


Review papers

Multiomics integration


Let's divide the scRNA-seq analysis workflow in two parts:

  1. Generation of cells and the expression matrix

  2. Computational analysis of the expression matrix




1- Generation of cells and the expression matrix

Experimental design

2- Computational analysis of the expression matrix

Data integration

Droplet identification

Doublet inference

Normalization

Batch effect correction

Batch effect are technical noise such as the time the experiment was done, the person carrying out the experiment or differences in reagents, etc. To correclty apply batch effect correction to a dataset, the experiment cannot be confounded (i.e., each bach must contatin at least two biological conditions).

Recommended tools as in Tutorial: guidelines for the computational analysis of single-cell RNA sequencing data. Nature Protocols, 2021. One important point is that even applying mutual-nearest-neighbors (mnn) tools between cells, one may incorrectly remove real biological signals if applied to a confounded experiment.

Data imputation

Marker genes identification

Cluster annotation and marker genes

Co-expression

RNA velocity

Gene Regulatory Network

Biclustering
