MaxQuant is a tool for quantitative proteomics, designed for analysing large mass-spectrometric data. It takes files with high-resolution, quantitative MS data and produces information about quantification of proteins and PTMs. It can be used for analysing data derived from any major relative quantification techniques (Label-free quantification (LFQ), MS1-level labelling and isobaric MS2-level labelling). Furthermore, it provides quantification algorithms for all common forms of tandem mass (TMT) and isobaric tags for relative and absolute quantitation (iTRAQ) labelling (including higher-plex TMT and multinotch MS3 quantification).

GENESIS Association Results Plotting creates Manhattan and QQ plots from GENESIS association test results with additional filtering and stratification options available. This app with it’s default options is the part of a GENESIS Association testing workflows, however after the association testing is completed users can fine-tune the Manhattan and QQ plots by running this app separately.

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.
