BFST(1)			     bFst (VCF statistics)		       BFST(1)

NAME
       bFst

SYNOPSIS
       bFst  -target  0,1,2,3,4,5,6,7  -background  11,12,13,16,17,19,22 -file
       my.vcf -deltaaf 0.1

DESCRIPTION
       bFst is a Bayesian approach to  Fst.   Importantly  bFst	 accounts  for
       genotype	 uncertainty  in  the model using genotype likelihoods.	 For a
       more detailed description see: `A Bayesian approach to inferring	 popu-
       lation  structure  from dominant	markers' by Holsinger et al. Molecular
       Ecology Vol 11, issue 7 2002.  The likelihood function has  been	 modi-
       fied  to	 use  genotype likelihoods provided by variant callers.	 There
       are five	free parameters	estimated in the model:	 each  subpopulation's
       allele frequency	and Fis	(fixation index, within	each subpopulation), a
       free parameter for the total population's allele	frequency, and Fst.

OPTIONS
	      Output : 11 columns :
		   1.  Seqid
		   2.  Position
		   3.  Observed	allele frequency in target.
		   4.  Estimated allele	frequency in target.
		   5.  Observed	allele frequency in background.
		   6.  Estimated allele	frequency in background.
		   7.  Observed	allele frequency combined.
		   8.  Estimated allele	frequency in combined.
		   9.  ML estimate of Fst (mean)
		   10. Lower bound of the 95% credible interval
		   11. Upper bound of the 95% credible interval

	      required:	t,target     --	a zero bases comma separated list of target individuals	corrisponding to VCF columns
	      required:	b,background --	a zero bases comma separated list of background	individuals corrisponding to VCF columns
	      required:	f,file a     --	a proper formatted VCF file.  the FORMAT field MUST contain "PL"
	      required:	d,deltaaf    --	skip sites were	the difference in allele frequency is less than	deltaaf

	      Type: statistics
