Genome Nexus Annotation Pipeline
These tools allow for annotation of genomic variants from a MAF for import into the cBioPortal using Genome Nexus
MAF Annotation
The annotationPipeline module is a command line tool to annotate a maf using genome nexus.
To use it, build the project using maven and run it like so:
mvn clean install
$JAVA_HOME/bin/java -jar annotationPipeline/target/annotationPipeline-0.1.0.jar --filename <INPUT_MAF> --output-filename <OUTPUT DESTINATION> --isoform-override <mskcc or uniprot>
You can choose to replace the gene symbols in the new maf by the gene symbols found by Genome Nexus by supplying the -r optional parameter. To output error reporting to a file, supply the -e option a location for the file to be saved. By running the jar without any arguments or by providing the optional parameter -h you can view the full usage statement. If you have your own installation of Genome Nexus, you can point to it by modifying the application.properties file located in annotationPipeline/src/main/resources.
Direct Database Annotation
If you have data already loaded into a cBioPortal database but did not properly annotate it or discovered issues later, you can use the databaseAnnotator utility to fix it.
You will need to specify some database connection parameters inside the application.properties file located in databaseAnnotator/src/main/resources. Once this is done, build the project using maven and run like so:
$JAVA_HOME/bin/java -jar databaseAnnotator/target/databaseAnnotator-0.1.0.jar --isoform <mskcc or uniprot>
As with the above tool, running the jar without any arguments or by providing the optional parameter -h will bring up the full usage statement. You can also specify a single study or set of studies to annotate by using the --studies parameter.
Annotator
The annotator module is the client code that makes calls to the Genome Nexus server and interprets the response. The other two modules use this as a dependency.
