Description
- SnpEff
- Genetic variant annotation and effect prediction toolbox. It annotates and predicts the effects of variants on genes (such as amino acid changes).
- Features
- Supports over 8,500 genomes.
- Cancer variants analysis
- GATK compatibile (-o gatk)
- HGSV notations support (clinical)
- SnpSift
- SnpSift helps filtering and manipulating genomic annotated files (VCF). Once you annotated your files using SnpEff, you can use SnpSift to help you filter large genomic datasets in order to find the most significant variants
Required Modules
Serial
- snpeff
System Variables
- HPC_{{#uppercase:snpeff}}_DIR - main installation directory
- HPC_{{#uppercase:snpeff}}_BIN - directory with executable scripts
- HPC_{{#uppercase:snpeff}}_CONF - directory with the default configuration file.
Additional Information
In SnpEff-4.x series the upstream project provides a shell script 'snpEff', which can be used to run the program without calling java directly.
For snpeff/3.3h we provided a 'snpeff' wrapper that made running snpeff easier. For example,
java -Xmx2g -jar $HPC_SNPEFF_DIR/jar/snpEff.jar download -c $HPC_SNPEFF_CONF/snpEff.config -v athalianaTair10
could be run simply as
snpeff download -v athalianaTair10
To override the default 2g java memory setting use the following command on the command-line or in a job script:
export _JAVA_OPTIONS="-Xmx4g"

Reference Databases
Note: as of March 21st, 2016 we have a full mirror of snpeff/4.2 reference databases released by the upstream project, so please do not request addition of new reference databases unless you provide a set of custom fasta and annotation files for building a custom database.
