SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires mellon, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill identifies genes that are crucial for driving cell fate decisions during developmental processes, by analyzing gene expression changes along inferred cell trajectories.

Core Features & Use Cases

  • Pseudotime-Associated Gene Discovery: Uses Adaptive Threshold Regression (ATR) to find genes whose expression significantly correlates with pseudotime.
  • Lineage-Specific Fate Gene Scoring: Identifies genes that specifically drive the progression of particular cell lineages using density estimation and variability scoring.
  • Use Case: After inferring cell differentiation trajectories in a single-cell RNA-seq dataset, use this Skill to pinpoint the key genes responsible for transitioning cells from a progenitor state to specific terminal fates.

Quick Start

Run CellFateGenie to identify genes driving cell fate decisions along the pseudotime trajectory in your annotated AnnData object.

FAQPage Schema
How do I identify genes driving cell fate decisions along pseudotime in single-cell RNA-seq data?

To identify genes driving cell fate decisions along pseudotime, apply Adaptive Threshold Regression (ATR) to your single-cell RNA-seq data to discover genes whose expression significantly correlates with the inferred developmental trajectory.

What is pseudotime-associated gene discovery and how does it work?

Pseudotime-associated gene discovery uses Adaptive Threshold Regression to find genes whose expression significantly correlates with pseudotime values in single-cell RNA-seq data, pinpointing key regulators of developmental progression.

Do I need pre-computed pseudotime values to perform trajectory inference gene analysis?

Yes, you need pre-computed pseudotime values in your annotated AnnData object to perform trajectory inference gene analysis, as the Skill requires these values to map gene expression changes along the developmental trajectory.

Can I find lineage-specific fate genes using density-based manifold analysis?

Yes, you can find lineage-specific fate genes using density estimation and variability scoring, which identifies genes that specifically drive the progression of particular cell lineages when optional clustering defines the lineages.

What's the best way to score lineage-specific genes in single-cell trajectory data?

The best way to score lineage-specific genes in single-cell trajectory data is using density-based manifold analysis and variability scoring to identify genes specifically driving particular cell lineage progressions from progenitor to terminal states.
