Introducing BulkRNA-Agent: AI-Powered Transcriptomics Analysis Made Easy 🧬🤖

TL;DR: BulkRNA-Agent is a free, open-source tool that combines artificial intelligence with traditional bioinformatics to revolutionize bulk RNA-seq analysis. With dual LLM architecture, interactive visualizations, and 100% local processing, it's designed for researchers who want powerful insights without compromising data privacy.

The Problem with Traditional RNA-seq Analysis 😓

If you’ve ever analyzed bulk RNA-seq data, you know the pain points:

  • Steep Learning Curve: R, Bioconductor, command-line tools… the barrier to entry is high
  • Fragmented Workflow: Jump between multiple tools for QC, DE analysis, and enrichment
  • Design Complexity: Choosing the right design formula feels like navigating a maze
  • Interpretation Challenges: You get a list of differentially expressed genes… now what?

Enter BulkRNA-Agent 🚀

BulkRNA-Agent is my answer to these challenges. It’s an AI-powered tool that brings intelligence to every step of the RNA-seq analysis pipeline.

🎯 What Makes It Unique?

1. Dual LLM Architecture

Unlike other tools, BulkRNA-Agent uses TWO specialized language models:

  • Reasoning Model (gpt-oss:20b): Handles tool selection, analysis planning, and statistical decisions
  • Biomedical Model (biomistral): Provides expert interpretation of gene functions, pathways, and biological context

This dual approach ensures you get both computational accuracy AND biological insight.

2. AI-Powered Design Suggestions 🧠

Stuck on what design formula to use? The agent analyzes your metadata and suggests optimal designs with explanations. No more guesswork!

3. Complete Pipeline in One Place

Upload Data → QC → Differential Expression → Enrichment → Chat with Your Results

Everything flows seamlessly in an intuitive web interface.

4. Privacy First 🔒

Your data never leaves your machine. Everything runs locally using Ollama, so sensitive patient data stays secure.

How It Works 🛠️

Installation (3 Steps!)

# 1. Install Ollama and models
ollama pull gpt-oss:20b
ollama pull cniongolo/biomistral

# 2. Clone and install
git clone https://github.com/shivaprasad-patil/BulkRNA-Agent.git
cd BulkRNA-Agent
./install.sh

# 3. Launch!
./start.sh

Open your browser to http://localhost:7860 and you’re ready to go!

Example Workflow

Step 1: Upload Your Data 📁

  • Count matrix (genes × samples)
  • Sample metadata (conditions, treatments, etc.)

Step 2: Quality Control ✅ The agent filters low-count genes and generates QC plots to ensure data quality.

Step 3: Get Design Suggestions 💡 The AI analyzes your metadata and suggests:

~ condition + batch
~ treatment * genotype
~ 0 + group

With explanations for each!

Step 4: Run Differential Expression 📈 One click, and you get:

  • Normalized counts
  • Statistical results for all contrasts
  • Interactive volcano and MA plots
  • List of significant genes

Step 5: Enrichment Analysis 🎯 Automatically runs GO, KEGG, and Reactome analysis on your significant genes.

Step 6: Chat for Insights 💬 Ask the AI questions about your results and get intelligent, context-aware answers.
