ZORRO

ZORRO merges multiple pre-assembled contigs into a consensus eukaryotic genome assembly to improve contiguity and correctness for downstream genomic analyses.

Key Features:

• Hybrid Assembly Approach: Integrates outputs from different assemblers to generate a consensus assembly that can improve contiguity and correctness compared with individual inputs.
• Pre- and Post-Assembly Treatment: Applies pre- and post-merging treatments to minimize errors and enhance the accuracy of the final assembly.
• Evaluation Metrics: Assesses contiguity, correctness, coverage, and duplication ratio to evaluate the quality of the merged assembly relative to input assemblies.

Scientific Applications:

• Genome assembly reconciliation: Reconciles multiple assemblies to produce a more contiguous consensus assembly for eukaryotic genomes.
• Gene annotation: Provides higher-contiguity assemblies that support more accurate gene model annotation.
• Comparative genomics: Supplies improved assemblies for genome-wide comparative analyses.
• Evolutionary studies: Facilitates evolutionary inference by reducing fragmentation and improving completeness of eukaryotic genome assemblies.

Methodology:

Performs an extensive comparative evaluation of various assembly reconciliation tools on a common dataset, measuring contiguity, correctness, coverage, and duplication ratio, and reports variability among tools with potential for increased contiguity when starting from high-quality inputs.
