SnpEff and SnpSift

SnpEff ( http://snpeff.sourceforge.net/ ) is a variant annotation and effect prediction tool by Pablo Cingolani.
It annotates and predicts the effects of variants on genes (such as amino acid changes).

This repository contains a tool_dependencies.xml file that downloads and installs SnpEff and SnpSift (SnpEff.jar and SnpSift.jar)

The install creates an environment variable: SNPEFF_JAR_PATH that contains the path to the jar files. Tools using this can generate a command line:
java -Xmx6G -jar \$SNPEFF_JAR_PATH/snpEff.jar eff -c \$SNPEFF_JAR_PATH/snpEff.config ...

The snpEff.config file is also installed, which specifies the default location for installed SnpEff genome databases:
data_dir = ~/snpEff/data/

The location of a genome database can be set via the commandline option -dataDir. Tools using this can generate a command line:
java -Xmx6G -jar \$SNPEFF_JAR_PATH/snpEff.jar eff -c \$SNPEFF_JAR_PATH/snpEff.config -dataDir path_to_data_directory snpeff_database_name input.vcf

Another way to change the location of data_dir would be to create a symbolic link in the galaxy HOME directory:
ln -s genome_data_path/snpEff ~/snpEff
