Pipes within VCF INFO Column
Sorry if this has been posted before but I cannot find an answer anywhere. I am trying to make sense of the INFO column of a .vcf file that was generated using whole exome sequencing (Illumina). Specifically, what do the number of pipes mean in the data below (| vs || vs ||||, etc.). Thanks!

pipe '|' is just a separator '||' means that there is a missing value.
You should have a look at the ANN spec for snpEff: http://snpeff.sourceforge.net/VCFannotationformat_v1.0.pdf
