Differential Expression

Volcano Plot Generator:
Transcriptomics & Proteomics Visualization

An interactive web-based tool for generating publication-quality volcano plots. Visualize differentially expressed genes with customizable fold change and significance thresholds. Features automatic classification (Up/Down/Not Significant), smart labeling, and statistical summary.

Up-regulated Detection

Automatically identify and visualize significantly up-regulated genes based on log2 fold change and adjusted p-value thresholds.

Down-regulated Analysis

Precise detection of down-regulated features with customizable statistical cutoffs and confidence intervals.

Smart Labeling

Intelligent gene labeling system based on marker selection or statistical significance thresholds with repulsion algorithms.
