ampvis

ampvis visualizes and analyzes microbial community data derived from 16S rRNA gene amplicon sequencing to support interpretation of community composition and dynamics.

Key Features:

• Data Handling and Integration: Processes OTU-tables (Operational Taxonomic Units tables) generated from 16S rRNA gene amplicon sequencing and integrates sample metadata for downstream analyses.
• Visualization Capabilities: Produces flexible static visualizations including heatmaps and ordination plots generated using the ggplot2 package.
• Ordination Methods: Implements simplified ordination methods for multivariate community analysis.
• Interactive Visualization: Provides interactive visualization options for exploration of larger and more complex datasets.

Scientific Applications:

• Microbial community analysis: Characterizes community structure and dynamics from 16S rRNA gene amplicon datasets.
• Metadata-driven ecological inference: Integrates sample metadata to correlate microbial composition with environmental or experimental variables.

Methodology:

Converts raw DNA sequencing data into OTU-tables via established pipelines and generates static plots with ggplot2 as well as interactive visualizations for data exploration.
