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

Operations

There is an extensive list of operations that can be executed with the Variant Storage Engine. There operations are:
