I want to use this tool here from GATK:
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?
