How Can AI Agents Run Immune Pathway Analysis from Bulk RNA-seq Data?

Learn how the AIPOCH Immune Pathway Analysis skill automates GSVA and ssGSEA scoring, limma differential ranking, and heatmap generation for bulk RNA-seq workflows.

AIPOCHMay 31, 2026

AI agents can support a complete immune pathway GSVA or ssGSEA — from a normalized or preprocessed expression matrix to ranked differential results and heatmap PDF — without researchers writing a single line of R code. The AIPOCH Immune Pathway Analysis skill accepts three CSV files, runs GSVA scoring across a user-supplied immune gene-set table, applies limma differential analysis to GSVA or ssGSEA pathway scores between two predefined sample groups supplied in group_info.csv, and produces structured tables and a heatmap for researcher review.

Pathway analysis methods like GSVA have been validated in published literature since Hänzelmann et al. (BMC Bioinformatics, 2013), which reported that GSVA can provide increased statistical power to detect subtle pathway activity changes over a sample population in comparison to PLAGE, ssGSEA, and combined z-score methods under the simulation conditions evaluated in that study.

Despite its methodological maturity, setting up a reproducible GSVA pipeline for immune Reactome gene sets still requires coordinating R package dependencies, writing limma differential analysis code, formatting gene-set tables in the correct long format, and generating consistent heatmap outputs — a setup process that can require significant preparation time before any biology is reviewed. AIPOCH's Immune Pathway Analysis skill can assist researchers in reducing this setup overhead so teams can focus on interpreting pathway rankings rather than debugging R environments.

What Does the Immune Pathway Analysis Skill Do?

The AIPOCH Immune Pathway Analysis skill can assist researchers with running immune pathway GSVA or ssGSEA analysis from a bulk expression matrix, a sample group file, and a local immune Reactome gene-set table, then export differential pathway results and a heatmap for two-group comparison.

When Not to Use

  • Immune cell fraction estimation or deconvolution
  • Gene-level differential expression without pathway scoring
  • Single-cell clustering, annotation, or communication analysis
  • Clinical diagnosis or treatment selection This skill only covers bulk immune pathway GSVA or ssGSEA analysis from a local immune gene-set table.

Workflow Execution Example

Immune Pathway Analysis

As shown in the first screenshot, a researcher provides three CSV files to the OpenClaw agent environment:

  • expression_matrix.csv
  • group_info.csv
  • immune_genesets.csv The researcher's prompt specifies the comparison direction (Tumor versus Healthy), the scoring focus (interferon signaling and antigen processing pathways), and the output type (heatmap).

Step 2 — AI Workflow Execution

Immune Pathway Analysis

The second screenshot shows the agent's execution progress:

  1. Expression matrix load: 506 genes × 8 samples; 19 immune Reactome gene sets built from the local table; 4 Tumor and 4 Healthy confirmed.
  2. GSVA scoring
  3. Limma differential analysis
  4. Ranking and output: 19 pathways scored and ranked for researcher review. Top hit: REACTOME_RUNX1_AND_FOXP3_TREGS (logFC = 0.58, p = 0.029). No pathways passed FDR ≤ 0.05; ranked by |t|-statistic.

Step 3 — Structured Outputs

  • immune_gene_set_summary.csv
  • immune_pathway_diff.csv
  • immune_pathway_scores.csv
  • immune_pathway_scores_top.csv
  • immune_pathway_heatmap.pdf

Who Can Benefit From This Skill

  • Computational biologists running repeated immune pathway comparisons
  • Translational medicine teams preparing pathway activity summaries from bulk RNA-seq datasets for manuscript figures
  • Bioinformaticians supporting wet-lab collaborators who need pathway heatmaps without managing R pipeline infrastructure
  • Graduate students and postdocs learning pathway analysis workflows with a reproducible, well-documented execution model

Conclusion

The skill reduces the repetitive workflow overhead of gene-set formatting, parameter configuration, group reconciliation, and heatmap regeneration — tasks that are consistent across projects but consume meaningful researcher time when handled manually. Biological interpretation of pathway rankings remains the researcher's responsibility.

FAQ

What inputs does the Immune Pathway Analysis skill require?

The skill requires three input files:

  1. A bulk expression matrix
  2. A sample group file
  3. A local immune Reactome gene-set table These files are used to calculate pathway-level GSVA or ssGSEA scores, compare pathway activity between sample groups, and generate structured output tables and heatmap visualizations.

What does the Immune Pathway Analysis skill not cover?

This skill only covers bulk immune pathway GSVA or ssGSEA analysis from a local immune gene-set table. It does not perform:

  • Immune cell fraction estimation or deconvolution
  • Gene-level differential expression without pathway scoring
  • Single-cell clustering, annotation, or communication analysis
  • Clinical diagnosis or treatment selection
