Hi there,

I'm using ANNOVAR to annotate variants from somatic sequencing data. I first annotate my VCF files with snpEff, which accurately picks up on mutliple variants at a single locus. I then annotate with ANNOVAR, which seemingly is unable to handle the comma separating variants, and only annotates the first in a comma delimited list of variants. Here is an example: I have in order, chromosome, position, REF, ALT, snpEff_Allele, and REVEL score. The REVEL score should be 0.545 for row 1, and 0.698 for row 2 and 3.

chr4    118705648   G   A,C  A      0.545    
chr4    118705648   G   A,C  C      0.545
chr4    118705648   G   C      C      0.698

According to documentation, ANNOVAR should be able to handle this kind of format but seemingly not? This is the code I used to run ANNOVAR.

module load annovar/2018-04-16
