GRAF

Building a better reference genome

Our award-winning reference genome tool.

GRAF at a glance

Canonical Linear Reference genomes are now 20+ years old and do not account for all genomic variation. Read mapping against linear references leads to reference bias. This systemic blindness is a profound barrier to accurate genomic data analysis, especially in non-European populations.

GRAF for discovery

Run fast and accurate genomic analyses using genome graphs. GRAF represents genetic variation in a population by enhancing the standard reference. The canonical linear reference serves as the backbone while edges represent alternate sequences.

GRAF for pan genome-aware secondary NGS analysis

Velsera has pioneered graph reference-based secondary analysis technology since 2014. The technology and patent portfolio are now available as robust, stable, scalable, and deeply validated pipelines ready for deployment in pharma discovery environments. The draft human pan-genome reference presented by the HPRC1 has generated broad awareness of how to solve the reference bias problem. State-of-the-art graph and pan-genome-based sequence analysis is now becoming the standard.

Why use GRAF

Improve alignment for compound variants

Known variants

The graph aligner aligns significantly more reads and accurately detects the variant as a homozygous insertion, while BWA erroneously detects it as heterozygous.

Identifying complex variants

Graph alignment facilitates the discovery of in-phase variants and other types of complex events.

Compound variants

A graph reference easily places variants within existing variants to facilitate alignment.

Across structural and point variants

Velsera’s GRAF solution provides data structures, algorithms, and graph references that effectively capture genomic diversity.

Real-world impact, trusted partnerships

“Using standard computational tools, we are already finding a large number of novel variants of African and Native American ancestries within the Brazilian genomes. We want to use the graph-based approach in order to capture the full value of our genomes.”
