SNP index definition

Question

[deniselavezzari]

Which is the definition of SNP index? Someone asked me to calculate the SNP index, but I cannot find a definition.

[WouterDeCoster]

You maybe could ask that 'someone' then? Not sure in which context this was asked, but SNP index doesn't ring a bell for me.

If you mean how to make index for VCF. Try following :

bgzip -c file.vcf > file.vcf.gz
tabix -p vcf file.vcf.gz
