Genetic Analysis - F_st

Title  Genetic Analysis - F_st

Summary

Use SPAGeDi to compute a variety of F_st, or F-statistics, on input data.


Usage

Syntax

SpagediFst (Input_Feature_Class, Population Field, Analysis_Type, Output_File)

Parameter Explanation Data Type
Input_Feature_Class Dialog Reference

Input dataset for computing F-Statistics against.

Feature Layer
Population Field Dialog Reference

Input dataset field which contains the populations used for comparison.

Field
Analysis_Type Dialog Reference

Jacknifing: mean jackknifed estimators and jackknife standard errors (SE) are computed for multilocus average statistics. They can be used to derive approximate confidence intervals using the mean ± 2SE. Jackknifying necessitates at least 2 polymorphic loci, but many polymorphic loci estimates are necessary to obtain reliable SE. Because SE are approximate, they should not be used for formal tests. (From SPAGeDI manual, §4.2.5)

String
Output_File Dialog Reference

A text file containing the results of the SPAGeDi analysis. Will be opened in the default text editor once analysis is complete.
