Go beyond somatic variant calling: GATK Somatic SNVs and INDELs (Mutect2) 4.1.9.0

The GATK Somatic SNVs and INDELs (Mutect2) 4.1.9.0 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 …

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 …

Multi-Omic Analysis at the Push of a Button

Increasing the simplicity and efficiency of running data analysis workflows in a consistent manner across a diverse set of users is a challenge faced by many biotech, diagnostic, and pharmaceutical companies. Manually gathering compatible input files from disparate sources, curating file metadata, starting multiple consecutive compute tasks, dealing with transient …

Harnessing the Cloud for Single-cell Research with the Seven Bridges Platforms

What is single-cell RNA sequencing analysis (scRNA-Seq)? The popularity of single-cell methodologies has seen an exponential rise in recent years.  Around 2010, the state of the art was examining only one cell by single-cell transcriptomics methods. Now we have the technology to analyze hundreds of thousands of cells in a …

Work Smarter, Not Harder: CWL and the Seven Bridges platforms

Seven Bridges is committed to ensuring reproducibility and portability of research analysis, and the use of Common Workflow Language (CWL) for tool and workflow descriptions helps to facilitate both. CWL is an open-source, community-driven specification and emerging standard for describing how to run computational analysis with command line tools in …
