2. BASIC SETTINGS
Number of randomizations (1-30,000):
For IBD plots, would you like a background grid?
Also perform analysis on Logarithmic (Genetic Distance)?
Also perform analysis on Logarithmic (Geographic Distance)?
Use negative genetic distances? (Otherwise, they will be set to zero.)
When log-transforming (genetic distance), negative genetic distances will be:


When log-transforming (genetic distance), set genetic distances of zero to:
Calculate RMA regression residuals?
3. RAW DATA SETTINGS
Analyze IBD with:



If two populations are fixed for the same allele, FST cannot be calculated. (There is no variance, so F is undefined). In these cases, what value should be substituted for FST? (Should be 0, or at least smaller than all other values, if you want to assume that the populations are identical.)
If F <=0, genetic similarity (M) is infinity. What value should be used for M[max]? (Should be slightly larger than the second highest M; you may need to return to this screen and change M[max] after examining the scatterplots.) This value will also be used if two populations are both fixed for the same allele.
If calculating Rousset's distance, what should genetic distances of 1.00 be set to? This value will also be used if two populations are both fixed for different alleles.
Calculate summary stats for each locus?
