snp frequency with annovar

Is it possible to get the snp frequency from a vcf population file ? I have been trying to add -withfreq to the table_annovar.pl command but it is not working

snp

did you add "-allsample" argument to your command?

nop as I didn't want x separate output files. I did run convert2annovar.pl with the -withfreq option but the result is not very good, there is even no column name

The frequency computed in convert2annovar.pl are somehow correct, it divide the snp appearance on the population by 2 times the total number individual which makes sense as 2 alleles per individual, but now my problem is that denominator to be 2 times pop minus the missing call for this snp
