SAUtils

Overview

SAUtils is a utility tool that creates binary supplementary annotation files (.nsa, .gsa, .npd, .nsi, etc.) from original data files (e.g. VCFs, TSVs, XML, HTML, etc.) for various data sources (e.g. ClinVar, dbSNP, gnomAD, etc.). These binary files can be fed into the Illumina Connected Annotations Annotation engine to provide supplementary annotations in the output.

The SAUtils Menu

SAUtils supports building binary files for many data sources. The help menu lists them out in the form of sub-commands.

You can get further detailed help for each sub-command by typing in the subcommand. For example:

dotnet SAUtils.dll clinvar
---------------------------------------------------------------------------
SAUtils (c) 2023 Illumina, Inc.
3.22.0
---------------------------------------------------------------------------

USAGE: dotnet SAUtils.dll clinvar [options]

More detailed instructions about each sub-command can be found in documentation of respective data sources.

Output File Formats

The format of the binary file SAUtils produce depend on the type of annotation data represented in that file (e.g. small variant vs. structural variants vs. genes).

.gsaCompact variant annotations (e.g. SNV, insertions, deletions, etc.)
.idxIndex file
.nsiInterval annotations (e.g. SV, CNVs, intervals)
.ngaGene annotations

.rmaReference Minor allele
.gfsGene fusions source
.gfjGene fusions JSON
.schemaJSON schema

SAUtils AutoDownloadGenerate

To make generating supplementary annotation files easier, we have provided an easier command that can be use instead of more granular subcommands. This subcommands basically integrate both download and generate subcommand. Currently, this subcommand support several data sources:

  • ClinVar
  • ClinGen
  • dbSNP
  • OMIM
  • COSMIC
dotnet SAUtils.dll AutoDownloadGenerate
---------------------------------------------------------------------------
SAUtils (c) 2024 Illumina, Inc.
3.23.0
---------------------------------------------------------------------------

USAGE: dotnet SAUtils.dll autodownloadgenerate [options]
Downloads and generates the Supplementary Database for Omim, ClinGen, ClinVar, dbSNP, and COSMIC

OPTIONS:
--sources, -s <VALUE> comma separated list of external data sources
--inputJson, -j <path> input JSON path
--downloadBaseFolder, -b <directory>
base directory path external datasources
downloaded to
--downloadDate, -d <directory>
date directory name that external datasources
downloaded to. Default is today's date in yyyy-
MM-dd format (e.g. 2023-01-30).
--cache, -c <directory>
input cache directory
--ref, -r <filename> input reference filename
--out, -o <VALUE> output SA directory
--actions, -a <VALUE> comma separated list of action(s) to perform.
action options: download, generate.
--help, -h displays the help menu
--version, -v displays the version

You can download only, generate only, or both download and generate supplementary files. To use this subcommands, you have to prepare a json file that will be used as data sources information. Below is tutorial to use this subcommand to generate each data source.

AutoDownloadGenerate ClinVar

Below is the command to use AutoDownloadGenerate for ClinVar to download and generate supplementary files.

dotnet SAUtils.dll AutoDownloadGenerate -s ClinVar -a download,generate -j [path to json] -c [path to cache folder] -r [path to reference folder] -b [path to folder to store downloaded files] -o [path to output folder]

The json file for ClinVar should be formatted like below:

{
"clinvar": {
"baseDirectory": "ClinVar",
"sourceFiles": [
{
"name": "ClinVar",
"description": "A freely accessible, public archive of reports of the relationships among human variations and phenotypes, with supporting evidence",

The json above is examplke for dbSNP version 156. If you want to use it for different version, adjust the version number and all entries in files to use the actual URL. If you only want to generate GRCh38, just remove the GRCh37 entries in the sourceFiles.

AutoDownloadGenerate OMIM

dotnet SAUtils.dll AutoDownloadGenerate -s OMIM -a download,generate -j [path to json] -c [path to cache folder] -r [path to reference folder] -b [path to folder to store downloaded files] -o [path to output folder]

"omim": {
"baseDirectory": "omim",
"sourceFiles": [
{
"name": "OMIM",
"description": "An Online Catalog of Human Genes and Genetic Disorders"
}
]
}
}

There is no need to modify the json entry for OMIM and you can use as it is. You have to export OMIM API key as environment variable with name OmimApiKey.

AutoDownloadGenerate COSMIC

dotnet SAUtils.dll AutoDownloadGenerate -s COSMIC -a download,generate -j [path to json] -c [path to cache folder] -r [path to reference folder] -b [path to folder to store downloaded files] -o [path to output folder]

}
]
}
}

You have to adjust the version entry according to which COSMIC version you want. You also need to have COSMIC credentials and export it as environment variable with name Cosmic_Username and Cosmic_Password
