How to Analyze Single-Cell RNA-seq Data – Complete Beginner’s Guide Part 5: Cell Type-Specific Differential Expression, Proportion Testing, and Functional Pathway Analysis
Introduction: From Cell Types to Biological Mechanisms In Parts 1-4 of this tutorial series, we’ve taken scRNA-seq data from raw sequencing reads through quality control, integration, clustering, and cell type annotation. We now have a beautifully annotated dataset where every cell has a biological identity (CD4+ T cells, monocytes, etc.) and metadata linking it to

How to Cluster RNA-seq Data to Uncover Gene Expression Patterns: Hierarchical and K-means Methods for Absolute Beginners
Introduction: Understanding Clustering in RNA-seq Analysis In the vast landscape of gene expression data, patterns often hide in plain sight. Among thousands of genes measured simultaneously, groups of genes may share similar expression patterns across samples, suggesting coordinated biological functions or responses. Clustering analysis serves as a powerful computational microscope that brings these hidden patterns

How To Analyze ATAC-seq Data For Absolute Beginners Part 2: Differential Binding Analysis Using DiffBind
Introduction: The Power of Comparative ATAC-seq Analysis ATAC-seq (Assay for Transposase-Accessible Chromatin with high-throughput sequencing) has revolutionized chromatin accessibility mapping by requiring minimal input material and offering streamlined workflows. While identifying accessible regions in a single condition provides valuable insights, the most compelling biological discoveries often come from comparing accessibility between different experimental conditions –

How to Analyze RNAseq Data for Absolute Beginners 21: A Comprehensive Guide to Batch Effects & Covariates Adjustment
Introduction to Batch Effects in RNA-seq Analysis In high-throughput sequencing experiments, batch effects represent one of the most challenging technical hurdles researchers face. These systematic variations arise not from biological differences between samples but from technical factors in the experimental process. Understanding and properly adjusting for batch effects is essential for generating reliable and reproducible

How to Analyze RNAseq Data for Absolute Beginners Part 20: Comparing limma, DESeq2, and edgeR in Differential Expression Analysis
Introduction Differential expression (DE) analysis represents a fundamental step in understanding how genes respond to different biological conditions. When we perform RNA sequencing, we’re essentially taking a snapshot of all the genes that are active (or expressed) in our samples at a given moment. However, the real biological insights come from understanding how these expression
