| 62 **What it does** | |
| 63 | |
| 64 The user specifies a SNP table and two "populations" of individuals, | |
| 65 both previously defined using the Galaxy tool to select individuals from | |
| 66 a SNP table. No individual can be in both populations. Other choices are | |
| 67 as follows. | |
| 68 | |
| 69 Data source. The allele frequencies of a SNP in the two populations can be | |
| 70 estimated either by the total number of reads of each allele, or by adding | |
| 71 the frequencies inferred from genotypes of individuals in the populations. | |
| 72 | |
| 73 After specifying the data source, the user sets lower bounds on amount | |
| 74 of data required at a SNP. For estimating the Fst using read counts, | |
| 75 the bound is the minimum count of reads of the two alleles in a population. | |
| 76 For estimations based on genotype, the bound is the minimum reported genotype | |
| 77 quality per individual. | |
| 78 | |
| 79 The user specifies whether the SNPs that violate the lower bound should be | |
| 80 ignored or the Fst set to -1. | |
| 81 | |
| 82 The user specifies whether SNPs where both populations appear to be fixed | |
| 83 for the same allele should be retained or discarded. | |
| 84 | |
| 85 Finally, the user chooses which definition of Fst to use: Wright's original | |
| 86 definition or Weir's unbiased estimator. | |
| 87 | |
| 88 A column is appended to the SNP table giving the Fst for each retained SNP. | |
