Annotation format for SNVs

Question

[Hamid]

Hello Biostars, I have a SNV annotations for a number of genes. They look like this: https://ufile.io/hyvs4

Can someone shed some light on this and tell me, 1. Why there are 3 rows for each position? 2. What software generates this type of annotation? 3. What is each column? I assume it is a standard format.

Thanks

Well, let's do some investigating here. From where did you obtain the file? Learning that may indirectly inform you of how it was produced.

Thanks, I found the header actually, for now, my main question is why do we have 3 lines per each snp? And what is the Ref and what is the Anc. The header for the first few columns is: Chrom Pos Ref Anc Alt Type Length
