GOsummaries

GOsummaries summarizes Gene Ontology (GO) enrichment results and integrates them with experimental data to support functional characterization of gene lists.

Key Features:

• Gene Ontology (GO) enrichment: Performs GO enrichment analysis on gene lists to identify significant GO terms.
• Word-cloud visualization: Visualizes GO enrichment results as concise word clouds representing dominant functional themes.
• Integration with experimental data: Displays graphs of raw experimental data alongside GO word clouds to link annotations with gene behavior such as differential expression or clustering.
• Multiple gene list handling: Combines word clouds from multiple gene lists into cohesive summary plots for comparative analysis.
• PCA annotation: Adds functional annotations to principal components to enhance interpretability of PCA results.
• Versatility across data types: Uses its PCA layout and association display beyond GO terms to support interpretation of metabolomics and metagenomics datasets.

Scientific Applications:

• Differential Expression Analysis: Aids identification of functionally relevant changes by displaying gene behavior alongside GO annotations.
• Clustering Analyses: Highlights common functional themes across clustered gene lists through summary visualizations.
• Principal Component Analysis (PCA): Improves PCA interpretability by integrating functional annotations with principal components.
• Metabolomics and Metagenomics interpretation: Supports interpretation when direct GO analysis is not feasible by annotating PCA and displaying significant associations.

Methodology:

Visualizes GO enrichment results as word clouds, combines word clouds across gene lists into summary plots, displays raw experimental data graphs alongside word clouds, and annotates principal components with functional terms.
