Overview

OpenCGA Variant Storage Engine provides a centralized solution to storage Genomic Variants. It provides a source of data for analysis and visualization in compatible viewers like GenomeMaps. Allowing a fast reading and filtering for variants will speed up analysis, with fastest and more accurate results.

There are an increasing number of biological formats supported by OpenCGA related with a common NGS pipeline. Within this formats, we focus on Genomic Variants due to the complexity and analysis capabilities.

Cohort stats

VCF types

• Aggregated VCFs: Variant files with no sample specific values. Just aggregated data
• Merged VCFs: Variant files with a batch of samples with specific samples data.
• gVCFs: Single sample files with information for all the positions.
