    • iVar consensus takes an aligned BAM file and generates a FASTA file with consensus sequences and a TXT file with average base qualities.
    • iVar getmasked takes a TSV file with variants generated by iVar tools, Primers BED file, and a TSV file with primer pair information and retrieves primers with mismatches to the reference sequence. Please note that this tool is only applicable to amplicon-based sequencing.

Recently published apps

We have just published the following apps:

  • An updated version of the SRA Download and Set Metadata workflow (SRA Toolkit 3.0.0) that downloads metadata associated with SRA accession via SRA Run Info CGI, (on-demand instance) FASTQ files and sets corresponding metadata.
  • OptiType (v1.3.5, CWL1.2), a tool designed for precision HLA typing from next-generation sequencing data. It is based on the assumption that the correct HLA genotype explains the highest number of mapped reads. Therefore, it searches for the best HLA allele combination of up to six major and six minor HLA-I alleles. The maximum number of reads potentially originating from one selection under the biological constraints that at least one and at most two alleles are selected per locus can be conveniently formulated as an ILP.
  • fastENLOC (v1.0, CWL1.2), a tool that enables integrative genetic association analysis of molecular QTL data and GWAS data. It performs integration of the results from molecular quantitative trait loci (QTL) mapping into genome-wide genetic association analysis of complex traits, with the primary objective of quantitatively assessing the enrichment of the molecular QTLs in complex trait-associated genetic variants and the colocalizations of the two types of association signals.

Recently published apps

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

  • TwoSampleMR, a tool that performs Mendelian randomization testing for a given exposure-outcome pair. It is a wrapper around the TwoSampleMR R package and uses summary statistics data for making causal inference.
  • CCS, a tool that combines multiple subreads of the same SMRTbell molecule and outputs one highly accurate consensus sequence.
  • lima, a tool used with PacBio single-molecule sequencing data for barcode and primer sequences identification.
  • PacBio Flowcell Data Processing, a workflow that can be used to process PacBio CCS or CLR data in preparation for variant calling.
  • PacBio CCS or CLR WGS Variant Calling workflow that can be used to call structural variants in PacBio CCS or CLR data. The workflow can also call small variants in CCS data using Clair3.
  • WARP WGS DRAGEN-GATK Single Sample, a WGS single sample processing workflow with DRAGMAP and GATK.
  • WARP TargetedSomaticSingleSample Pipeline, designed for somatic human targeted sequencing data analysis. The workflow takes human single sample uBAM input files which will be converted into FASTQ reads and mapped to a reference file. The obtained alignment files will be passed to the quality control tools, calculating and producing different quality metrics. Output targeted somatic alignment files can be further used for variant calling or other analyses by different tools/pipelines, while metrics outputs can give various quality and statistical calculations about input data and the produced alignment file.

Recently published apps

New apps have been added to the Seven Bridges Platform:

  • Two tools from the Samplot toolkit:
    • Samplot Plot takes alignment files and coordinates for a region containing the SV call of interest (Chromosome, Start position, and End position) and creates a plot of the SV region.
    • Samplot Vcf can be used to create visualizations of structural variant calls from a VCF file.
  • Seven tools from the Smoove toolkit:
    • Smoove Annotate annotates SV calls with SV quality and gene information from GFF3 files.
    • Smoove Call calls structural variants with Lumpy and optionally calls svtyper.
    • Smoove Duphold annotates SV calls in the file based on information from the provided alignment files.
    • Smoove Genotype runs svtyper in parallel on provided SV inputs.
    • Smoove Merge merges SV calls from individual files with SV calls and sorts them using svtools.
    • Smoove Paste squares matching SV calls from individual files to a single joint file with final calls.
    • Smoove Plot-counts takes a VCF file created by other Smoove tools and plots counts of split and discordant reads before and after filtering.
  • Upgraded four Sambamba tools to 0.8.1 (and CWL 1.2) and added three new tools:
    • Sambamba Flagstat generates statistics from read flags in a BAM file.
    • Sambamba Index creates a BAI or FAI index for the provided input.
    • Sambamba Markdup can be used to mark or remove duplicate reads from an input BAM file.
    • Sambamba Merge merges alignments in BAM format.
    • Sambamba Slice can be used to copy a slice (region) of the coordinate sorted and indexed input file in BAM or FASTA format.
    • Sambamba Sort sorts alignments in BAM format.
    • Sambamba View accepts alignments in BAM or SAM format and outputs data in a user-specified format.
  • Vcf2maf is a tool that converts VCF files to MAF files. To obtain a MAF file from a VCF, each variant must be mapped to exactly one gene transcript/isoform that it might affect, and be associated with exactly one effect. Vcf2maf invokes Variant Effect Predictor to choose the transcript and effect associated with each variant in the output MAF file.
  • Cancer Predisposition Sequencing Reporter tool that can be used to interpret germline variants in the context of cancer predisposition. The tool takes a VCF file with germline variants obtained from WES or WGS, cross-references the set with the user-selected set of genes of interest, annotates the variants and reports the associated information (ClinVar-classified variants, ACMG secondary findings, Variant biomarkers and GWAS hits).
  • Personal Cancer Genome Reporter can be used to analyze a VCF with somatic variants obtained using WES, WGS or targeted sequencing. It is a tool for functional annotation and classification of somatic variants.
  • Whole Genome Sequencing – Quality Control workflow, used for quality control of WGS data. The workflow is intended as a general-purpose QC workflow for users processing WGS data, offering plots which can be easily inspected, as well as structured data output suitable for aggregation and parsing in an automated setup (JSON and TAR.GZ archive with all QC files).

NewSupport for Nextflow and WDL workflows available on the Seven Bridges Platform

Apart from significant contributions from Seven Bridges team members to the development of the Common Workflow Language (CWL) and its extensive implementation on our Platform, we are now taking a step further and providing support for two more workflow description languages, Nextflow and WDL. This presents a groundbreaking move in the direction of enabling you to reduce the time needed to bring your apps to the Seven Bridges Platform, eliminate the need for conversion of your Nextflow or WDL code, while still allowing you to use a better interface for running workflows and all other out-of-the-box features in the Seven Bridges ecosystem. 

The process of bringing Nextflow and WDL apps to the Seven Bridges Platform is designed to be in line with the existing app development tools and practices and is a matter of using the existing Nextflow and WDL code, making configuration optimizations to get the maximum out of the Seven Bridges execution environment and using the sbpack utility to help with the optimization and the actual communication with the Seven Bridges Platform. To guide you through the process, the documentation describes the process for both Nextflow and WDL workflows.

This implementation is the initial release and will be under intensive development in the future. Further improvements will include performance improvements, such as the capability of running different parts of a Nextflow or WDL workflow on different compute instances, as well as many others that will significantly contribute to a better user experience.

ImprovementsRHEO – improved scaling and more elastic execution infrastructure

We have improved our automation execution infrastructure by enabling it to scale up its compute capacity automatically when there is an increased workload and a need for new automation runs to be initialized. In addition, we have introduced a limit of 30 parallel automation runs per Division as a measure of precaution to ensure proper use of the elastic automation execution service. Executions that require more than 30 parallel runs are still absolutely possible, as the limit can be increased if there is an actual need for more capacity. Please contact for more details.
