NewDRS notification improvements and the brand new Activity center

To provide you with more detailed information about each DRS import operation and enable you to resolve import issues independently, we have improved DRS-related notifications and implemented the Activity center, available by clicking Open activity center in the Activity feed. When any of the items from a particular DRS import fail, you will be able to see an error message and a corresponding error code for each of the items, allowing you to understand and try to fix the issue. Furthermore, a description and link to the relevant documentation will be provided for each import from a DRS server.

NewFile download restriction can now be activated for project files

To further improve security controls over data available on the Seven Bridges Platform, we have implemented the option to restrict downloading of files from platform projects. The restriction is  enabled per project, on project creation, along with optional parameters that prevent downloading of analysis output files and allow file copies to be present in other projects. Learn more about download restrictions.

This functionality is not available by default. To learn what your options are and have it enabled, please get in touch with your Velsera contact person or

We published Giraffe-DeepVariant workflow 1.0Cramino 0.9.7 and kyber 0.4.0 tools from the NanoPack2 toolkit, as well as Pisces tool, PureCN NormalDB workflow 2.6.4PureCN workflow 2.6.4zUMIs 2.9.7 tool, and AlphaFold 2.3.2 tool. Here are the details:

  • Giraffe-DeepVariant workflow 1.0 is a pipeline for calling small variants using the pangenome reference. The workflow starts with sequenced reads (FASTQs, CRAM). Reads are mapped to a pangenome with vg giraffe and pre-processed (e.g. indel realignment) before performing the variant calling step using DeepVariant.
  • Cramino 0.9.7 is a quick QC tool intended for long-read sequencing. It takes a BAM/CRAM format alignment file and creates a QC report with mean coverage, number of reads, their mean and median length and sequence identity relative to the reference genome.
  • kyber 0.4.0 creates a 600×600 pixel heatmap image of read length and read accuracy from input alignment file (BAM/CRAM format).
  • Pisces does variant calling from aligned amplicon sequencing data.
  • PureCN NormalDB workflow 2.6.4 builds a normal database which is used for coverage normalization in PureCN workflow.
  • PureCN workflow 2.6.4 estimates tumor purity and ploidy, copy number and loss of heterozygosity (LOH). Calculated purity and ploidy combinations are sorted by likelihood score. Copy number and LOH data are provided by both gene and genomic region. The steps in the workflow include: preparation of an interval file for further analysis, calculation of coverage for tumor and normal samples (optionally for additional tumors) and final calculation of purity, ploidy, copy number and LOH results.
  • zUMIs 2.9.7 takes RNA-seq data with or without UMIs, STAR index files archive and annotation GTF file and analyzes the data as specified by the other input parameters.
  • AlphaFold 2.3.2 is a machine-learning application which incorporates knowledge about physical and biological protein structure properties into a deep learning algorithm, and predicts protein structures with high accuracy.

Recently published apps

We published the following apps in our Public Apps gallery:

  • RADx-rad v0.2 Workflow, which is used for metagenomic data analysis of SARS-CoV-2 from wastewater samples. The workflow was developed and ported to CWL as a part of the RADx (Rapid Acceleration of Diagnostics) – the initiative to speed innovation in the development, commercialization, and implementation of technologies for COVID-19 testing, launched by The US National Institutes of Health (NIH).
  • CNVPanelizer 1.32.0, which generates a report table and visualization of detected CNVs from targeted sequencing data.
  • Control-FREEC 11.6 which can be used for somatic copy number analysis of WGS, WES and targeted data.

DRS import available on the Seven Bridges Platform

With the introduction of DRS import on the Seven Bridges Platform, you are now able to import files from either external sources or the Cancer Genomics Cloud (CGC). This also presents a significant improvement to data interoperability, as CGC users who have adequate authorizations can now successfully access CGC datasets from the Platform using DRS import. Imported files can then be used as any other file on the Platform.

Learn more about DRS import.

We have published the following apps in our Public Apps gallery:

  • VEP Slivar Trios Rare Diseases Analysis with VEP 109.3 version and Slivar 0.3.0 version inside. This analysis is used for preprocessing and analyzing variants from related individuals (trios or families; WES or WGS).
  • STAR-Fusion (v1.12.0), an app that uses the STAR aligner to identify candidate fusion transcripts supported by Illumina reads.
  • STAR-Fusion Build FusionFilter Dataset (v1.12.0) that creates the required CTAT genome lib archive for STAR-Fusion execution.
  • Cutadapt (v4.4), an app most commonly used for removing adapter sequences. It finds and removes adapter sequences, primers, poly-A tails and other types of unwanted sequences from high-throughput sequencing reads.
  • Seven tools from the Kalisto 0.48.0 toolkit:
    • kallisto quant computes equivalence classes for reads and quantifies transcript abundances from RNA-Seq data.
    • kallisto quant-tcc runs the EM algorithm on a supplied TCC matrix file to make transcript-level estimates.
    • kallisto bus produces BUS (Barcode-UMI-Set format) output files from single-cell RNA Seq datasets.
    • kallisto merge merges the results of several batches obtained by kallisto pseudo.
    • kallisto h5dump converts HDF-5-formatted results to plaintext.
