Recently published apps

  • GATK Somatic SNVs and INDELs (Mutect2) can be used to detect SNVs and INDELs in one or more tumor samples from a single individual, with or without a matched normal sample. Assembly implies whole haplotypes and read pairs, rather than single bases, as the atomic units of biological variation and sequencing evidence, improving variant calling.
  • GATK Somatic Create Mutect2 Panel of Normals workflow creates a panel of normals (germline and artifactual sites) for use in other GATK workflows. It takes multiple normal sample callsets produced by GATK Somatic SNVs and INDELs (Mutect2 workflow) tumor-only mode (although it is called tumor-only, normal samples are given as the input) and collates sites present in two or more samples into a sites-only VCF.

Both workflows are composed in reference to the official GATK’s WDLs.

ImprovementsImproved project organization with project tags 

In order to improve the organization and findability of projects, project tags have been introduced to the Seven Bridges Platform.

Project Admins can now assign tags to projects via the API or through the visual interface. Such tags can be used for filtering purposes when browsing all projects, for projects categorization, and for general custom organization of projects.

The maximum number of tags for a single project is 15, while the maximum number of characters in a single tag is 36. Learn more.

GDC Datasets version update

As of February 22, GDC datasets available through the Data Browser and the API correspond to GDC Data Release 27.0.

New password validation rules

In order to maintain a high level of security and prevent unauthorized access to the Seven Bridges Platform, we are introducing password checking against a database of commonly used passwords and those that were compromised in data breaches across the Internet, which is why they are considered unsafe. If the entered password exists in this database, you will need to use a different one. 

Additionally, please note that the entire password validation process takes place within the Seven Bridges infrastructure, which ensures an additional level of security as there are no third-party services involved. This password validation mechanism applies when trying to perform the following actions:

  • Sign up for a new account.
  • Set up a new password to replace an expired one.
  • Change the account password.

ImprovementsTask queueing improvements

We have made the following changes to the task queueing process that should improve the queueing logic and contribute to faster completion of initialized tasks and analyses:

  • If you reach your parallel instance limit with running tasks, and there are both tasks and Data Cruncher analyses waiting in the queue, Data Cruncher analyses will be first to execute once instances become available.
  • If the parallel instance limit is reached with tasks that are being executed, when an instance becomes available it will first be allocated to running multi-instance or scattered tasks if they need additional instances. If there are no such tasks, the instance will be allocated to other task(s) that are next up in the queue. This will enable faster completion of multi-instance and scattered tasks and help avoid breaks in their execution.

Recently published apps

GENESIS LocusZoom visualizes association testing results using the LocusZoom standalone software. This app is a wrapper around LocusZoom standalone software to enable it to work with outputs of GENESIS association pipelines. The main goal of this app is to visualize results of GENESIS Single Variant Association Test, however regions from sliding window or aggregate tests with p-values below a certain threshold can be displayed in a separate track.

SBG Loci Snapshoter generates screenshots of specific regions across all aligned files provided as inputs. It utilizes the IGV batch functionality to create PNG images of desired loci across multiple samples. The main driver of developing this tool was doing a post-association visualisation of associated variants across a subset of CRAM files used to obtain those variants.

ImprovementsData Cruncher Stability and Usability Improvements

Your experience with Data Cruncher just got better thanks to the following improvements:

  • Use the full potential of RStudio as it is now officially out of the BETA stage and its stable release is available in Data Cruncher.
  • Maintain full control over your workspace integration capabilities in a more secure environment – your Data Cruncher sessions are now run on a separate domain providing even better security isolation and privacy control of your favorite third-party integrated development environments.
  • Have a better insight into your session initialization phase with a more informative loading experience.
  • Find your way around with more ease – the top navigation bar provides access to analysis information, control options, documentation and feedback form, while the editor continues to provide native experience in your chosen base environment.
    • Seven Bridges addons for JupyterLab (i.e. the Project Files tab and the Save to project right click option) are now deprecated in favor of a unified and improved experience – delivering a more stable and up-to-date visual interface you’re familiar with.
  • Enjoy the cost control capabilities (Suspend time) without getting interrupted – your keyboard and mouse activity in the editor is now monitored as session activity in all available environments.
