\\
A program to detect loci that might be under selection in samples from structured populations.

===== Program information =====
  * Linux
  * DOS



===== Data type handled =====
  * Microsat
  * DNA
  * Standard (multi-allelic marker)



===== Input Files =====
==== fdist2 - this is the simulation program: ====
  * consists of 6 lines:
    * Total number of demes (100 max)
    * No of populations sampled (must be less than or equal to total number of demes)
    * Expected Fst for infinite allele, infinite island model
    * Sample size (assumed the same in all populations) 
    * Indicator - 1 for stepwise mutations; 0 for infinite alleles
    * No of realizations (loci) 

=== example ===
<code>
100
15
0.17
50
0
20000
</code>



==== datacal ====
  * 1/0 indicator: alleles by rows in data matrix (1), or pops by rows (0).
  * No of pops
  * no of loci
  * no of alleles at locus 1
  * matrix of data at locus 1 either with each row corresponding to the same allele or to the same population 
  * no of alleles at locus 2
  * matrix...
  * etc.
  * The data matrices can contain populations for which a locus was not genotyped, these should be indicated by zero entries
