SCRIP

SCRIP simulates single-cell RNA sequencing (scRNA-seq) data to reproduce biological variation and technical noise for benchmarking and method development.

Key Features:

• Accurate simulation of transcriptional dynamics: Simulates bursting kinetics to capture gene expression dynamics at single-cell resolution.
• Mean-variance dependency modeling: Reproduces mean-variance relationships across experimental conditions to enhance data fidelity.
• Cell-cell distance recovery: Recovers cell-cell distances more accurately than existing simulators to support clustering and transcriptome structure analysis.
• Method evaluation datasets: Generates simulated datasets for differential expression benchmarking, demonstrating that edgeR performs well and that ZINB-WaVE improves AUC at high dropout rates.

Scientific Applications:

• Sequencing protocol optimization: Provides realistic scRNA-seq datasets to compare and optimize experimental designs and sequencing parameters.
• Method benchmarking and validation: Enables evaluation and comparison of differential expression and analysis methods under controlled conditions.
• Development of analytical methodologies: Supports creation and testing of computational approaches for single-cell transcriptome analysis.

Methodology:

Implements a novel simulation framework that models bursting kinetics, mean-variance dependency, and biological variation to generate realistic scRNA-seq datasets.
