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

Sentieon Multi-instance Whole Genome Workflow

Organizations have adopted the use of Next Generation Sequencing (NGS) as a one of the primary tools of their discovery, diagnostic and clinical efforts. Simultaneously — the number of tools available for NGS analysis has ballooned, with each tool having different capabilities for speed, accuracy, cost, etc. Seven Bridges offers …

Data Cruncher Public Interactive Analyses

To help researchers transform raw NGS-based data into clinically actionable knowledge, Seven Bridges strives to efficiently bridge the gap between secondary and tertiary analysis. One of the features we offer to achieve this goal is Data Cruncher, which enables scientists to perform interactive computing and open-ended exploration of data on …

Taxanomic Profiling of Metagenomics Samples

Numerous colonies of different organisms live virtually everywhere on Earth, even in and on our bodies. They are called microbes and we think we know all about them. But do we really? Actually, the human race knew nothing about microbes before the 17th century. There were some assumptions and hypotheses, …

Accurate Analysis of Differential Methylation Data

With few exceptions, every human cell is composed of an identical DNA sequence. However, there are around 200 different cell types in our bodies. What is the underlying reason? Each different cell type represents a specific gene expression pattern. One of the main mechanisms that enables this is epigenetics. Epigenetics …

Optimized Workflow for Bisulfite Sequencing Data Analysis

Epigenetics is an extra layer of information that is not encoded in the primary sequence of an organism’s DNA. While several mechanisms of epigenetic regulation exist, DNA methylation is one of the most commonly studied ones. Typically, the presence of methylated cytosines within a promoter region represses gene expression. The …

Spatial Transcriptomics on the Seven Bridges Platform

As our understanding of biology deepens, many researchers are moving away from bulk gene expression analyses to single-cell analyses. However, current RNA-Seq methods that assay pooled RNA from tissue samples, or even from single cells, fail to conserve the spatial distribution of gene expression within the original tissue. In addition, …

How to Use Variant Filtering for Genomic Analysis

The variant filtering process consists of selecting highly confident variants and removing the ones that are falsely called. Secondary genomic DNA analysis is mainly oriented toward alignment and variant calling, assuming the accuracy of these two would provide a major influence on the overall quality. The variant filtering step used …
