I have a multi sample vcf file of a particular gene for 1000 individuals . I annotated it with snpeFF. I want to know that what amino acid and codon changes these variants are creating in each individuals . Also I want to know the position of amino acid change in the protein formed from these variants .In snpEff output summary file I am getting the overall codon and amino acid changes but I want to know the position of change and individual also. In short I want my annotation results be like that they show the position of amino acid and codon change in each individual by these variants . Kindly tell about some approach or tool for the same.
