Hi Everyone

Have anyone used annotation_variation.pl by Annovar to build a reference from NCBI build 37.1. I need this version exactly to annotate some old versions data. When I use UCSC hg19, the annotations makes less sense I think.

perl annotate_variation.pl -buildver b37 -downdb \
        -webfrom ftp://ussd-ftp.illumina.com/Homo_sapiens/NCBI/build37.1  Homo_sapiens_NCBI_build37.1  humandb/

I tried several url, I usually get:

NOTICE: Downloading annotation database ftp://ussd-ftp.illumina.com/Homo_sapiens/NCBI/build37.1/Homo_sapiens_NCBI_build37.1.txt.gz ... Failed WARNING: Some files cannot be downloaded, including ftp://ussd-ftp.illumina.com/Homo_sapiens/NCBI/build37.1/Homo_sapiens_NCBI_build37.1.txt.gz

I think it assumes the URL has the data file ends with .txt.gz. Any hint how to fix this? Having the full link doesn't work either

Thanks

Can you independently download the files first? Looks like -webfrom option is only to download from annovar servers.

-webfrom allows from URL too as the documentation . But if I download it, how can I use what I downloaded in the command?

I am not sure ANNOVAR can download from arbitrary URLs. It needs files to be in a specific format.

It would probably be a lot easier to convert your VCF to hg19 than to prepare the ANNOVAR input for your reference, especially if you want to use more than just gene info (ANNOVAR has a lot of other pre-built databases). See this earlier discussion: build37 against hg19

I will try that conversion. Thanks a lot igor.
