Hi,

I generated my vcf files from GATK pipeline using ploidy 1 as it is a mycobacterium tuberculosis genome. Now i want to annotate my variants using snpEFF and Annovar. I search snpEff database for mtb annotation using:

java -jar snpEff.jar download -v Mycobacterium_tuberculosis

it gave me numerous results showing that it contans the mtb database. Bit I'm not sure which one is mine/reference one that i used to generate the vcf file. My mtb reference genome file looks like this:

>M.tuberculosis_H37Rv NC_000962.3

I tried buildDbNcbi.sh script from snpEFF to build my own db but it is produced the following error:

Then i kept my fasta file in the above mentioned error folder but now it is giving the following error:

Downloading genome NC_000962.3

curl: (16) Error in the HTTP2 framing layer

Then i thought of using the built in db for MTB so i just renamed my chr names in my file it is: M.tuberculosis_H37Rv And i tried to replace it with the built in one: ERS007734SCcontig000001 Still no success.

It is generating the following error in each variant of the vcf file:

9;ANN=A||MODIFIER|||||||||||||ERROR_OUT_OF_CHROMOSOME_RANGE

Can anyone help me with this please and can anyone tell how to use annovar for same vcf file?

Thank you. :)
