Multiallelic VCF with annotation in INFO field doesn't query all available infromation

[KalinNonchev]

Hello,

I noticed that in the case of annotated multiallelic VCF where annotation for each alternative is stored in the INFO field, variant.INFO.get("annotation") would only pick the first occurrence.
Example:

1 123 A T,TA ... annotation:0.5.. annotation:0.1

variant.INFO.get("annotation") would return only 0.5 instead of [0.5, 0.1]

Hi, can you show the actual line from the VCF?
the INFO field is key=value, so you can't have the same key twice.
Format fields are separated by : as you have shown above.

That would be an example with multiple gnomad312_AF annotations... It looks like the annotations are separated by "ALLELE_END;"

chr1\t10340\t.\tT\tG,C\t;ANNOVAR_DATE=2020-06-08;gnomad312_AF=0.0014;ALLELE_END;ANNOVAR_DATE=2020-06-08;gnomad312_AF=0.0509;ALLELE_END\t

That is not VCF format. It might be a text format output by annovar?
