We have just updated the content of our public app galleries with new GATK releases:

  • GATK Pre-Processing For Variant Discovery workflow is used to prepare data for variant calling analysis. The workflow consists of two major segments: alignment to reference genome and data cleanup operations that correct technical biases. Resulting BAM files are ready for variant calling analysis and can be further processed by other BROAD best practice pipelines, like Generic Germline Short Variant Per-Sample Calling workflow, Somatic CNVs workflow, and Somatic SNVs + INDELs workflow.
  • GATK Generic Germline Short Variant Per-Sample Calling workflow that calls germline variants in a WGS sample with GATK HaplotypeCaller, starting from an analysis-ready BAM file.

And six GATK tools:

  • GATK GatherBQSRReports tool that gathers scattered BQSR recalibration reports into a single file.
  • GATK BaseRecalibrator tool that generates a recalibration table based on various covariates for input mapped read data.
  • GATK ApplyBQSR tool that recalibrates the base quality scores of an input BAM or CRAM file containing reads.
  • GATK HaplotypeCaller tool for calling germline SNPs and indels from input BAM file(s) via local re-assembly of haplotypes.
  • GATK VariantFiltration tool used for filtering variants in a VCF file based on INFO and/or FORMAT annotations.
  • GATK MergeVcfs, used for combining multiple variant files.

We’ve just published four tools from the OncoGEMINI 1.0.0 toolkit:

  • OncoGEMINI Bottleneck that identifies somatic variants with increasing allele frequency in longitudinal data.

  • OncoGEMINI Loh, a command tool that performs loss of heterozygosity analysis.

  • OncoGEMINI Truncal that recovers variants that appear in all tumor samples, but are absent in the normal sample.

  • OncoGEMINI Unique tool for identifying somatic variants unique to a subset of samples.

Billing information just got more informative and organized

The following improvements have been made on the Billing page available to Enterprise and Division administrators:

  • The Billing page has been redesigned and now consists of three sections: Billing information, Instance limits and Payment information.
  • The start date from which costs are calculated is now displayed for the current billing period.
  • Additional charges and credits information is now renamed to Charges and Refunds and grouped in the Additional subsection.
  • Total Platform charges now sum up costs for Analysis, Storage and Additional charges.

SBG Image Processing Toolkit 

SBG Image Processing Toolkit consists of apps that enable various stages of machine learning image processing. Seamless integration between the tools of this toolkit provides an easy and logical analysis flow, while enabling support of various data types, preprocessing steps and utilizing computation capabilities of the Seven Bridges Platform.

  1. SBG Deep Learning Image Classification Exploratory Workflow is an image classifier pipeline that relies on the transfer learning approach. This allows the use of pre-trained models as the starting point for building a model adjusted to given image datasets. Furthermore, the pipeline allows training of the model for a variety of hyperparameter combinations in parallel by utilizing multiple GPU instances, while detailed metrics and visualizations help determine the best configuration that can later be used to make predictions on new data instances. 
  2. SBG Deep Learning Prediction is an image classifier tool that classifies unlabeled images based on labeled data. It is intended as a final step after the SBG Deep Learning Image Classification Exploratory Workflow. Testing different configurations in parallel with the exploratory workflow and finding the best model configuration for the given dataset, then using SBG Deep Learning Prediction with that configuration and all available labeled images as the training data provides the optimal training conditions which lead to the best classification results.
  3. SBG Histology Whole Slide Image Preprocessing takes SVS histopathology images, removes various artifacts, and outputs the desired number of best quality tiles in PNG format that consist of at least 90% tissue.
  4. SBG X-Ray Image Preprocessing Workflow performs the selected X-ray image enhancement algorithm: unsharp masking (UM), high-frequency emphasis filtering (HEF) or contrast limited adaptive histogram equalization (CLAHE). 
  5. SBG Stain Normalization involves casting an array of images in the stain colors of a target image. Stain normalization is used as a histopathology image preprocessing step to reduce the color and intensity variations present in stained images obtained from different laboratories.
  6. SBG Medical Image Convert performs medical image format conversion. If the input data are medical images in a non-standard format (e.g. SVS, TIFF, DCM or DICOM), SBG Medical Image Convert converts them to PNG format.
  7. SBG Split Folders organizes an image directory into the train and test subdirectory structure. These directories are necessary inputs for SBG Deep Learning Image Classification Exploratory Workflow and SBG Deep Learning Prediction.


HistoQC is an open-source quality control tool for digital pathology slides. It performs fast quality control to not only identify and delineate artefacts but also discover cohort-level outliers (e.g., slides stained darker or lighter than others in the cohort). It outputs an interactive user interface for easy viewing and understanding of the results.


Minimac4 is a genetic imputation algorithm that can be used to impute genotypes in a genomic region starting from a reference panel in M3VCF format and pre-phased target GWAS haplotypes.


BOLT-LMM is a tool that tests the association between genotypes and phenotypes using a linear mixed model.

GSEAPreranked Workflow performs Gene Set Enrichment Analysis (GSEA). It is generated with an assumption that a differential expression analysis has been done before using the DESeq2 tool which is publicly available on the Seven Bridges Platform. The GSEAPreranked Workflow consists of two tools, GSEA Input Prepare and GSEAPreranked. The GSEAPreranked tool represents a wrapper around the command-line tool that was developed by the BROAD Institute. The GSEA Input Prepare tool is based on the Python script developed by the Seven Bridges team to prepare the required input file formats for the GSEAPreranked tool.
