align3d

align3d reconstructs chromosome conformation from images of fluorescently-tagged genomic loci to infer three-dimensional chromosomal architecture for studies of genome organization.

Key Features:

• Enhanced Reconstruction Algorithm: Implements an improved algorithm that increases reconstruction accuracy of chromosome conformation compared to prior methods.
• Scalability: Handles large-scale problems, accommodating several hundred labeled loci in a single reconstruction.
• Resolution Capabilities: Demonstrates via simulations the potential to achieve full-chromosome reconstructions at a resolution of 1/2 megabase (Mb).
• Fluorescent Loci Input: Operates on images of fluorescently-tagged genomic loci where each locus is marked with a distinguishable color.

Scientific Applications:

• Visualize Chromosome Architecture: Reconstructs three-dimensional chromosome conformations from labeled-loci images to reveal nuclear organization.
• Study Gene Regulation: Enables investigation of how spatial genome organization relates to gene expression and regulatory interactions.
• Investigate Disease Mechanisms: Supports identification of structural chromosome anomalies that may contribute to genetic disorders.

Methodology:

Processes images of fluorescently-tagged genomic loci—with each locus marked by a distinguishable color—using an enhanced reconstruction algorithm to infer the spatial arrangement and conformation of chromosomes, and employs advanced simulations to evaluate potential full-chromosome reconstruction at 1/2 megabase resolution.
