SYNOPSIS

popStat –type PL –target 0,1,2,3,4,5,6,7 –file my.vcf

DESCRIPTION

General population genetic statistics for each SNP

OPTIONS

  Calculates basic population statistics at bi-allelic sites. The allele frequency is the number of non-reference alleles divided by the total number of alleles.  The expected hetrozygosity is 2*p*q, where p is the non-reference allele frequency and q is 1-p.  The observed heterozgosity is the fraction of 0/1 genotypes out of all genotypes.  The inbreeding coefficient, Fis, is the relative heterozygosity of each individual vs. compared to the target group. 
Output : 9 columns :                 
     1. seqid                        
     2. position                     
     3. target allele frequency      
     4. expected heterozygosity      
     5. observed heterozygosity      
     6. number of hets               
     7. number of homozygous ref     
     8. number of homozygous alt     
     9. target Fis
