Overview

The BD RhapsodySequence Analysis Pipeline is a versatile tool that offers the flexibility to run your bioinformatics analysis on either a Seven Bridges cloud-based platform or on a local installation.


The BD RhapsodySequence Analysis Pipeline:

  • Provides a primary analysis of single-cell multiomics data by leveraging cutting-edge algorithms to deliver fast results and deep insights.
  • Utilizes an intuitive user interface via a cloud-based platform and is easy to use, regardless of the computational expertise of the user.
  • Offers the ability to choose between cloud-based or local installation options and affords maximum convenience and accessibility for single-cell multiomics data analysis.
  • Provides broad compatibility of output data with downstream analysis tools such as Seurat and Scanpy.

 

 

 

Pipeline Overview

After sequencing, the pipeline takes input from FASTQ files, a reference (Targeted panel or WTA genome archive), an AbSeq reference (if required), and a supplemental reference (if required), using those to generate molecule counts per cell and metrics about the pipleline run.

 

Release notes

v2.2.1 BD Rhapsody™ Sequence Analysis Pipeline

June 05, 2024

 

Additions

  • Support for MGI sequencer FASTQ read header and file names
  • For TCR/BCR assay, new output of a compressed bundle of PNG images showing the per chain VDJ DBEC algorithm thresholds
  • Long read support - added new pipeline parameter for enabling support for long R2 reads (>650 bp) - default is to auto-detect long or short reads

 

Updates

  • Ability to customize STAR and BWA-MEM2 alignment parameters, enabled on Seven Bridges and local runs

 

Fixes

  • Failures that could occur with MGI sequencer FASTQ files in the QualCLAlign or AlignmentAnalysis nodes
  • Failure caused by VDJ AssembleAndAnnotate node – Argument list too long
  • Failure caused by MergeBam node – Argument list too long
  • PhiX aligned reads could incorrectly be counted as targeted mRNA reads when using a targeted panel (usually these are already removed during FASTQ generation)

 

v2.2 BD Rhapsody™ Sequence Analysis Pipeline

April 19, 2024

 

Additions

  • Added support for ATAC-Seq Assay and Multiomic ATAC-Seq Assay (WTA+ATAC-Seq)
  • Added ability to customize STAR alignment parameters

 

Updates

  • Updated the immune cell type classifier to be more lenient in the percentage of bioproducts required to run
  • Updated TCR BCR annotation software IGBlast to version 1.22
  • Updated TCR BCR annotation to IMGT release 202349-3 (12-06-2023)
  • Updated bead version detection

 

Fixes

  • Fixed error in dimensionality reduction when zero variable genes are found due to very sparse data
