A standalone and free application to explore genetics variations from VCF file


Cutevariant is a cross-plateform application dedicated to maniupulate and filter variation from annotated VCF file. When you create a project, data are imported into an sqlite database that cutevariant queries according your needs. Presently, SnpEff and VEP annotations are supported. Once your project is created, you can query variant using different gui controller or directly using the VQL language. This Domain Specific Language is specially designed for cutevariant and try to keep the same syntax than SQL for an easy use.
