  • use snpEff to annotate vcf file

    Dear all,

    I am a green-hand for SNP analysis. I use GATK generate the vcf file for staph aureus. Now I need to add annotation to it.

    I tried snpEff, how every I get errors

    java -Xmx4g -jar snpEff.jar eff -v -c snpEff.config NC_003923.1 snp.filtered.vcf >test.vcf
