We have introduced the option to archive apps that you don’t intend to use in a project. Archiving will hide an app from the apps list, workflow editor and other relevant places across the Platform. However, this will not affect reproducibility, as you will be able to rerun existing tasks containing the app.
Archived apps can be displayed by changing the Status filter to Archived in the apps list within a project. To restore an app, click Restore next to the desired archived app.
Find out more about app archiving in our documentation.
Multi-Instance Whole Genome Sequencing GATK4.0 Workflow
We’ve published the Multi-Instance Whole Genome Sequencing BWA/GATK 4.0 workflow. This workflow keeps a similar price, with the improvement in total execution time of up to 3.0 times compared to a single-instance implementation. The Multi-Instance Whole Genome Sequencing workflow processes a 30x whole genome in as little time as 3 hours without any additional computational resource such as GPU or FPGA. The differences in precision, recall and f-score between multi-instance and single-instance workflows are lower than 0.001%, which is expected due to stochastic effects.
See the workflow on the Seven Bridges Platform.
NewSpatial Transcriptomics Pipeline with Spotty
Spatial Transcriptomics is a method that allows visualization and quantitative analysis of the transcriptome in individual tissue sections. Spatial Transcriptomics Pipeline with Spotty is a workflow for processing raw sequence data (paired FASTQ-files) generated using the Spatial Transcriptomics technology. The workflow produces a table of spatially distributed gene counts for downstream analysis.
This workflow consists of two nested workflows:
- ST Pipeline which performs demultiplexing and decoding of the RNA-Seq reads.
- The Spotty workflow with post processing, to perform automatic spot identification and pairing between the fluorescent (Cy3) and tissue (HE) image. Spotty is proprietary and available only on the Seven Bridges platform environments.
Read more about the workflow on our blog.
NewData Cruncher Interactive Analyses – Public project
As a part of the effort to grow a comprehensive set of platform features and capabilities, we have developed several Data Cruncher Interactive Analyses as an additional resource that should help users mitigate challenges related to interpretation of data obtained through secondary analysis. These Data Cruncher analyses can be found in the Data Cruncher Interactive Analyses public project.
The project contains five analyses:
- Ballgown Interactive Analysis
- VCF visualization Interactive Analysis
- Structural variation Interactive Analysis
- ChIP-seq Interactive Analysis
- Microbiome Differential Abundance Analysis
Each Interactive Analysis comes with explanations of analysis steps and a corresponding set of files needed for successful execution.
NewSupported instances update
The new generation of AWS EC2 Compute Optimized instances (C5) and General Purpose instances (M5) is now also available in task executions and Data Cruncher analyses on eu.sbgenomics.com. See the full list of supported AWS EU instances in our documentation.
NewAPI bulk actions
Due to popular demand, we have created several new API bulk calls. The calls allow users to perform an operation on up to 100 files within a single API call, while using only one API rate limit. This results in significantly faster completion of operations involving a big number of files.
Currently we have bulk calls implemented for the following operations:
- bulk imports from a volume
- bulk exports to a volume
- bulk get file details (stat files)
- bulk delete files
- bulk edit files
The calls have also been implemented in our Python client, with Java and R client implementation coming up in the near future.
Rabix Composer v1.0 Release
We’ve released the initial version of Rabix Composer (v1.0), which includes significant improvements over the beta version with respect to the development of CWL 1.0 and sbg:draft-2 applications on your local machine.
For more details about the Rabix Composer v1.0 release, please refer to the latest Rabix release note. Also, keep an eye out for further updates and improvements to this initial release.
Key new features in Rabix Composer v1.0:
- We have integrated Rabix Executor into the Composer, so you can now develop and test your CWL app through a single user interface.
- When you edit a tool or workflow on the Seven Bridges Platform, you will see the Edit with Rabix Composer button.
- Rabix Composer is now also available for Windows.
Set suggested files for workflow inputs
We’ve introduced the option to set files from public projects as suggested for a file input in a workflow. This will allow anyone who runs the workflow to use the suggested files as inputs in a single click, and only have to add the remaining input files manually. Please refer to documentation for more details.
Folders on the visual interface
We have introduced support for folders on the Seven Bridges Platform. To complement our existing API functionalities, now you can organize your project files into folders through the Platform’s visual interface, which allows you to have a better overview of your files and manage them more easily. Some of the currently available options related to folders are the ability to copy and move files between folders, use the optional sidebar tree for browsing, search recursively inside the folder structure and use files from folders as task inputs. In the upcoming period we will be working on adding more options to folders, such as the ability to rename a folder, output task results into a folder and many more.
Uploaders have also undergone some changes in order to add folder support. Two major features are introduced:
- uploading items (files and/or folders) into folders;
- preserving folder structure when uploading items.
Smart Variant Filtering
The variant filtering process consists of selecting highly confident variants and removing the ones that are falsely called. This process used to be mostly left out from deeper testing in secondary genomic DNA analyses, even though it can boost precision of variant calls significantly. After developing graph genome alignment tool and reassembly variant caller, we are now launching the Smart Variant Filtering tool used for filtering germline variants.
Smart Variant Filtering (SVF) uses machine learning algorithms trained on features from the existing Genome In A Bottle (GIAB) variant-called samples (HG001-HG005) to perform variant filtering (classification). The comparison results obtained during deep, three-stage testing demonstrate that it outperforms the solutions currently used within most secondary DNA analyses. Smart Variant Filtering increases the precision of called SNVs (removes false positives) by up to 0.2% points while keeping the overall f-score higher by 0.12-0.27% points than in existing solutions.

TLS 1.0 and TLS 1.1 no longer supported
We have removed support for TLS 1.0 and TLS 1.1 protocols. The only supported protocol on our Platform and API is TLS 1.2. If you are using a client that does not support TLS 1.2, please perform an upgrade to continue using the Seven Bridges Platform.
More about the TLS protocol
The TLS (Transport Layer Security) protocol is a cryptographic protocol that provides communications security in a computer network. It’s a successor of the SSL (Secure Sockets Layer) protocol that is now prohibited from use by IETF. TLS provides both confidentiality and data integrity in transit between two communicating computers. TLS version 1.2 is a modern version of this protocol that enables highest possible communication security between your application/browser and our Platform/API. The deprecated versions, TLS 1.0 and TLS 1.1, have a number of known weaknesses, and it is in the best interest of our users to use the up-to-date version.
If you are using Internet Explorer, make sure that you upgrade your browser to version 11 or later. If you are using an up-to-date version of Chrome, Firefox or Safari – you are all set.
If you have any follow-up questions, feel free to contact the Seven Bridges Support Team.
