We blog about genomics. We also make a platform for open-source analysis of next generation data in the cloud. Hello.

Machine Learning and Image Processing on the CGC: Tools For Success

Machine learning is becoming ubiquitous in the bioinformatics space: applying machine learning algorithms to analysis of proteomics, genomics, and other -omics datasets has provided a wealth of analysis and interpretations of data not easily achievable by conventional methods. The CGC offers many helpful features for users performing machine learning (ML) …

Multi-Omics Analysis on the CGC: Applications in Epigenetics Research

The growing diversity of large cancer datasets has led to increased capabilities for multi-omics research. Multi-omics analysis is a promising approach to reveal the functionality of complex biological systems and processes. However, multi-omics analysis is a complex process that needs to be carefully designed and conducted, beginning from sampling all …

GATK Best Practices Spotlight: The GATK Somatic Create Mutect2 Panel of Normals workflow

The GATK Somatic Create Mutect2 Panel of Normals (PON) workflow takes multiple normal sample callsets produced by GATK Somatic SNVs and INDELs workflow tumor-only mode (although it is called tumor-only, normal samples are given as the input) and collates sites present in two or more samples into a sites-only …

Go beyond somatic variant calling: GATK Somatic SNVs and INDELs (Mutect2)

The GATK Somatic SNVs and INDELs (Mutect2) workflow is a somatic variant caller workflow that uses local assembly and realignment to detect single nucleotide variants (SNVs) and insertion and deletion (INDEL) changes. This Mutect2 tool (see the original publication on BioRxiv) is an improvement upon the original “MuTect” tool …

The Data Repository Service API on Seven Bridges: Towards Global Interoperability

For the first time ever, users on CAVATICA are able to import datasets from NHLBI BioData Catalyst powered by Seven Bridges, such as TOPMed, onto the CAVATICA platform for analysis. Likewise, users on NHLBI BioData Catalyst can import Kid’s First Datasets from CAVATICA in the same manner. Before now, there …

Accurate sequencing data analysis for under-represented populations: The Pan-African genome

We are excited to announce the release of our GRAF Population Solution, a set of tools, services, and workflows  that enable the construction of genome graph references for targeted populations and/or studies. In this blog post, we discuss some of the advantages of population-specific graphs compared to  methods that rely …

The Annotation Explorer: 1 billion variants, hundreds of annotations, and just a few minutes

With the ongoing proliferation of genome sequencing data, the number of rare variants found is growing rapidly. To detect associations between phenotypes of interest and these rare variants, researchers employ mechanisms to increase statistical power in association testing. Variant annotation information can be used to combine variants into biologically-relevant units …
