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.

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.

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.
    • kallisto index builds an index from a transcriptome FASTA formatted file of target sequences.
    • kallisto inspect outputs the target de Bruijn Graph from the kallisto index file in different file formats.

We published the following tools from the GATK and ensembl-vep 109.3 toolkits:

  • GATK BaseRecalibrator, which generates a recalibration table based on various covariates for input mapped reads.
  • GATK ApplyBQSR, which recalibrates the base quality scores of an input BAM or CRAM file containing reads.
  • GATK GatherBQSRReports, which gathers scattered BQSR recalibration reports into a single file.
  • GATK HaplotypeCaller, which calls germline SNPs and indels from input BAM file(s) via local re-assembly of haplotypes.
  • GATK VariantFiltration, which is used for filtering variants in a VCF file based on INFO and/or FORMAT annotations.
  • Augmented Filter VEP, which is a customized wrapper of the filter_vep script from the ensembl-vep toolkit. The tool is modified to allow GNU parallel-scattered filtering of VEP-annotated VCFs split on chromosomes.
  • Variant Effect Predictor, which predicts functional effects of genomic variants and is used to annotate VCF files.

In addition, the VEP annotation workflow 109.3 is also live and available in the Public Apps gallery. It is used for preprocessing, annotating, and filtering VCF files using the vt toolkit and VEP.

We also published the PURPLE CNV Calling Workflow used for somatic CNV calling and purity and ploidy estimation on WGS data. It is based on PURPLE 3.7.2, and consists of two additional tools – AMBER and COBALT. The workflow first calculates B-allele frequency (BAF) with AMBER and read depth ratios with COBALT, which is then used by PURPLE to estimate the purity, ploidy and copy number profile of a tumor sample.

RHEO becomes more flexible and robust

For an improved experience of creating code packages and running automations in RHEO, we have introduced several improvements that are already live and ready to be used:

  • When creating code packages, you can now select which Python version to use in order to maintain reproducibility, but also benefit from the features available in more recent Python versions. The available options are Python 3.6, 3.7 and 3.8, with 3.8 being the default version if this parameter is not specified.
  • The new AWS execution mode enables automation runs directly on AWS Fargate instances instead of using the available RHEO execution infrastructure. AWS execution mode is activated using a dedicated configuration parameter.
  • Improved stability and monitoring of automation runs executed both on the RHEO execution infrastructure and AWS Fargate.
