What problem does it solve?
This Skill provides an efficient and scalable solution for storing, querying, and exporting large genomic variant datasets, overcoming the limitations of traditional VCF/BCF file handling.
Core Features & Use Cases
- Efficient Storage: Utilizes TileDB's sparse array technology for compressed and optimized storage of variant data.
- Scalable Ingestion: Handles large VCF/BCF files and supports incremental addition of new samples.
- High-Performance Querying: Enables rapid querying of specific genomic regions and samples.
- Data Export: Allows exporting subsets of data in standard VCF or TSV formats.
- Use Case: Analyze allele frequencies across thousands of samples for specific genomic regions in a large cohort study, or quickly retrieve all variants for a particular gene from a multi-terabyte VCF dataset.
Quick Start
Use the tiledbvcf skill to create a new TileDB-VCF dataset named 'my_dataset' and ingest the samples from 'sample1.vcf.gz' and 'sample2.vcf.gz'.
