Software Overview

Parabricks is a software suite for genomic analysis. It delivers major improvements in throughput time for common analytical tasks in genomics, including germline and somatic analysis. The core of the Parabricks software is its data pipeline, which takes raw data and transforms it according to the user's requirements.

Parabricks supports the tools shown below:

Parabricks supports the pipelines shown below:

pb_pipelines2.png

The Parabricks software can be configured to run specific accelerated tools or run full pipelines that are commonly used. The standalone tools page covers individual tools and the pipelines page discuses how to run commonly used pipelines.

NVIDIA Parabricks pipelines have been tested on Dell, HPE, IBM, and NVIDIA servers at Amazon Web Services, Google Cloud, Oracle Cloud Infrastructure, and Microsoft Azure.

Pipelines

In Clara Parabricks, each pipeline is a collection of several individual tools that are commonly used together, all wrapped up as a single tool. For example, the deepvariant_germline takes FASTA and FASTQ files as input and produces a VCF and BAM file as output. Internally, it runs BWA mem alignment, performs coordinate sorting, marks duplicates, and then runs DeepVariant.
