GNET2

GNET2 constructs gene regulatory networks (GRNs) from transcriptomic gene expression data using a probabilistic graphical model to map regulatory interactions between genes.

Key Features:

• Integrated R package: Implemented as a cohesive R package for execution and integration within R-based analysis workflows.
• Probabilistic graphical model: Uses a probabilistic graphical model to infer regulatory interactions from transcriptomic data.
• Flexible parameter initialization: Provides configurable parameter initialization to adapt the model setup to dataset-specific characteristics.
• Iterative modeling process: Employs an iterative modeling framework to refine regulatory module construction and network inference.
• Data exchange integration: Automates data exchange between components within an R session to support computational data flow.
• Scalability for large datasets: Designed to handle large-scale transcriptomic datasets for network inference at increased data volumes.

Scientific Applications:

• GRN inference: Infer gene regulatory networks from high-throughput transcriptomic gene expression datasets.
• Pathway and interaction analysis: Explore gene interactions and regulatory pathways derived from inferred networks.
• Functional genomics and disease research: Support functional genomics studies, disease modeling, and identification of potential therapeutic targets.

Methodology:

Preprocess transcriptomic data, construct a probabilistic graphical model from the expression data, and iteratively refine the inferred network to represent gene regulatory relationships.
