dbsnp file for C. elegans

Question

[biomagician]

Hi,

I want to use this tool here from GATK:

https://software.broadinstitute.org/gatk/documentation/tooldocs/current/org_broadinstitute_gatk_tools_walkers_varianteval_VariantEval.php

VariantEval

It has the optional option to input a dbsnp file --dbsnp. Does anybody know where I can find such a file for C. elegans?

Also, what is a dbsnp file? I know that dbsnp is a database (https://www.ncbi.nlm.nih.gov/projects/SNP/) but is it also a format or does the dbsnp file come in VCF format?

Thanks.

Best wishes,

C.
