NVT

NVT evaluates normalization methods for RNA-Seq differential gene expression analysis as an R package by comparing normalization strategies via correlation analyses.

Key Features:

• Normalization Method Evaluation: NVT assesses a range of normalization techniques for RNA-Seq data to reveal method-specific assumptions and performance.
• User-Defined Gene Sets: Analysis can use user-defined sets of uniformly expressed genes to anchor comparisons among normalization methods.
• Correlation-based Visualization: The package produces visualizations representing correlation values among normalization strategies to compare method agreement.
• Evaluation across Experimental Conditions: NVT enables comparison of normalization performance under different experimental conditions.

Scientific Applications:

• Differential Gene Expression Analysis: Supports selection of normalization approaches to improve reliability of detected differentially expressed genes in RNA-Seq studies.
• Normalization Method Benchmarking: Enables benchmarking and comparison of normalization strategies across datasets and experimental conditions.

Methodology:

NVT compares normalization strategies by computing correlation values among methods using a predefined or user-defined set of uniformly expressed genes.
