We have published the Bracken 2.7 toolkit:

  • Bracken (Bayesian Reestimation of Abundance with KrakEN) tool is used for abundance estimation at the species level, the genus level, or above.
  • Bracken Build is used to prepare the reference database for Bracken.

In addition, Metagenomics Profiling – Kraken2 workflow has been published on the Platform. It is used for metagenomic classification, abundance estimation, and visualization.

We have also published the following tools:

  • FlowSOM 2.4.0 which presents an algorithm used to distinguish cell populations from both flow and mass cytometry data in an unsupervised way.
  • cytofkit2 0.99.80 which is designed to analyze mass cytometry data from FCS files. It includes preprocessing, cell subset detection, cell subset visualization and interpretation, and inference of subset progression.
  • flowAI 1.24.0 which performs quality control on FCS data acquired using flow cytometry instruments. By evaluating three different properties: flow rate, signal acquisition, and dynamic range, the quality control enables the detection and removal of anomalies.

We have recently published the following apps:

  • SBG Single-Cell RNA Deep Learning – Training, a single-cell classifier pipeline for human data. It relies on the transfer learning approach, which uses pre-trained gene embeddings as the starting point for building a model adjusted to given single-cell datasets.
  • SBG Single-Cell RNA Deep Learning – Predict, a single-cell classifier pipeline for human data. This app uses the deep learning model generated by the SBG Single-Cell RNA Deep Learning – Training workflow to classify the input dataset.

  • CNVkit scatter plots bin-level log2 coverages and segmentation calls together.
  • CNVkit metrics calculates the spread of bin-level copy ratios from the corresponding final segments.
  • CNVkit heatmap draws copy number for multiple samples as a heatmap.
  • CNVkit genemetrics identifies targeted genes with copy number gain or loss above or below a threshold.
  • CNVkit call calls absolute integer copy number for each segment in segmented log2 ratio estimates.
  • CNVkit batch is a copy number calling pipeline wrapped into a single tool.

We have published the following apps:

  • SBG Pair FASTQs by Metadata CWL1.2 tool, which accepts a list of FASTQ files and groups them into sub-lists based on the metadata. The sbg:draft-2 version of this tool will also remain available in the Public Apps gallery.
  • Upgraded version of the MultiQC (v1.13, CWL1.2) tool, which aggregates results from bioinformatics analyses across many samples into a single report. This wrapper version of MultiQC can also accept inputs from files that were produced by the Salmon Workflow (salmon_quant_archive.tar).

NewSeven Bridges CLI now available for macOS ARM users

In order to make sure all of our users have uniform experience and can make the most out of the Seven Bridges Platform, the Seven Bridges Command Line Interface (SB CLI) is now also available for macOS ARM (M1/M2) users. The new build allows the growing population of users using Apple computers with M1 and M2 chips to install the SB CLI and interact with the Platform from the command line. The macOS ARM version of the SB CLI is available for download from the Platform’s Data Tools section and from the related documentation page.

Disabled accounts can now be reactivated in a snap

Accounts that are locked or disabled due to inactivity can now be automatically reactivated by their owners. A new, streamlined flow allows you to initialize the process by sending a reactivation email to your email address after logging in with your last used credentials. By clicking the link in the email and setting a new password on the platform, you will have unrestricted access to your account and data again.

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

  • Mosdepth 0.3.3 toolkit: Mosdepth, a tool used for fast depth calculation on WGS, WES or targeted BAM and CRAM files and Mosdepth plot_dist which plots Mosdepth results.
  • Personal Cancer Genome Reporter 1.0.3 which is used for functional annotation and classification of somatic variants.
  • Cancer Predisposition Sequencing Reporter 1.0.0 which analyzes cancer-predisposing germline variants.

We have also updated versions and published tools from the following two toolkits: SRA (v3.0.0, CWL1.2) and Salmon (v1.5.2, CWL1.2). Tools that got the update are:

  • SRA sam-dump that converts SRA data into SAM format. With aligned data, NCBI uses Compression by Reference, which only stores the differences in base pairs between sequence data and the segment it aligns to. The process to restore original data, for example as FASTQ, requires fast access to the reference sequences that the original data was aligned to.
  • SRA fasterq-dump that converts SRA data into FASTQ format while using temporary files and multi-threading to speed up the extraction.
  • SRA fastq-dump that converts SRA data into FASTQ format.
  • Salmon Alevin that introduces a family of algorithms for quantification and analysis of 3’ tagged-end single-cell sequencing data.
  • Salmon Index that builds an index necessary for the Salmon Quant and Salmon Alevin tools. To create an index, it uses a transcriptome reference file in FASTA format. Additionally, one can provide a genome reference along with the transcriptome to create a hybrid index compatible with the improved mapping algorithm named Selective Alignment.
