ASV Read Count Dataset #1: Full Amplicon Sequence Variant Abundance Table

A full dataset containing the number of reads per sample for every Amplicon Sequence Variant inferred by the dada2 pipeline. Taxonomy was assigned using the Python packages blast and basta. The dataset was authored by Alejandro Maeda Obregon and last updated on April 28, 2026.

Use Cases

• Calculate alpha and beta diversity metrics based on ASV read counts.
• Compare microbial community composition across samples based on inferred ASVs.
• Perform differential abundance analysis based on the per-sample read counts.
• Validate taxonomy assignation pipelines based on the blast and basta results.

Strengths

• Dataset is described as the 'Full dataset', suggesting completeness for the described analysis.
• Taxonomy assignation was performed using established bioinformatics tools (blast and basta).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
