vcfanno fails to parse header of bcf file

[edg1983]

Hello,

I'm using vcfanno 0.3.3 to annotate a bcf file that has undergone several previous processing steps, including bcftools fill-tags, bcftools filter, bcftools csq.

I'm using a toml config file that worked fine before so I assume this is OK.

Essentially, it seems vcfanno has problems parsing the header of the input bcf as you can see from the error log below

I've attached the actual header of the file if this can help you understand the issue.

Thanks a lot!

Hi @edg1983 ,
vcfanno doesn't support BCF. I should add a better message for that, but it will resolve your issue for now.

Oh I didn't realized that!
I got confused by the error message.

Easy fix then! ;)

Thanks!
