Topmouth Culter Genomic Data for Inversion-Linked Loci Analysis

A restricted set of 15 inversion candidates was identified from public genomic resources for the freshwater fish Topmouth culter (Culter alburnus). The data includes results from benchmarking scaffolding strategies and reconciling structural-variant calls, culminating in a focal set of three loci (INV_20, INV_40, INV_50) that show strong north-south genomic differentiation. This 31.6 KB dataset, authored by kai liu and last updated in 2026, is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Identifying genomic loci linked to chromosomal inversions based on assembly-aware filtering.
• Evaluating allele-frequency differentiation between north and south fish populations.
• Analyzing local population-genomic context, such as linkage disequilibrium and principal components, around inversion intervals.
• Benchmarking structural-variant calling and scaffolding strategies using public assemblies and resequencing data.

Strengths

• Dataset is derived from a 123-individual resequencing panel, providing a population-level sample.
• Analysis includes 15 inversion candidates filtered through multiple assembly-comparison routes and high-fidelity long-read support.
• Results are focused on three specific loci (INV_20, INV_40, INV_50) with strong support for differentiation.

Limitations

• The dataset is very small at 31.6 KB, indicating limited scope or summary-level data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
