Immanc: Version 5.0 (8 Oct 1998)
Detecting Immigrants Using Multilocus Genotypes.


BayesAss+: Version 1.3 (Date 4 May 2005)
Bayesian Estimation of Recent Migration Rates Using Multilocus Genotypes.


BayesAss: Version 2.0 (not released yet)
BayesAss is a program that estimates recent migration rates between populations using MCMC. It also estimates each individual’s immigrant ancestry, the generation in which immigration occurred (i.e. the individual can be assigned as an immigrant from a specific population, a non-immigrant, or the offspring of an immigrant and a non-immigrant), the population (as opposed to the sample) allele frequencies, inbreeding (F) values within each population, and genotypes at any locus with missing data.

Program information

  • Windows
  • Linux
  • Mac OSX

Data type handled

  • diploid data
  • microsatellites
  • RFLPs
  • SNPs
  • Standard
  • allozymes

Input Files

  • suffix of .inp or .txt
  • Two file formats are currently accepted by BayesAss: Structure format and Immanc format

Structure format

  • first column: individual label
  • the second: population label
  • the remaining columns: the alleles
  • labels:
    • each label must be unique (either a unique individual or population)
    • Alphabetical characters, strings, and (positive or negative) numbers may be used
  • two rows are expected for each diploid individual (data must be diploid!)

example

  • data for 10 individuals, with 5 individuals sampled from each of 2 populations, and each individual genotyped for 4 loci:
    ind0 0 0 0 A 0  
    ind0 0 1 0 1 1
    1.1  0 0 2 0 2 
    1.1  0 0 1 1 0  
    2    0 2 1 0 2 
    2    0 1 0 1 2 
    3    0 1 1 B 1 
    3    0 2 2 0 0  
    4    0 0 2 0 2  
    4    0 2 1 1 0  
    joe  1 0 1 0 1 
    joe  1 0 2 2 0  
    11   1 2 1 2 1 
    11   1 1 2 0 1  
    12   1 2 2 1 0  
    12   1 1 2 1 0 
    13   1 2 1 0 2  
    13   1 1 1 2 2  
    ann  1 1 1 1 0  
    ann  1 0 2 2 1 

Immanc format

  • Columns can be separated by any whitespace
  • Missing genotypes should be represented by 0, 00, or 000
  • Blanks are not allowed
  • first column: individual label
  • the second: population label
  • the third: locus label
  • the remaining 2 columns: the alleles at each locus that make up a genotype
  • Spaces within names are not allowed
  • each individual has a row entry for every locus
  • the order of the alleles determines the haplotype phase (this information is not currently used and so the ordering is arbitrary)
  • (ignore text after %)

The setup for the data file should be:

Individual1	population1	locus1	allele1	 allele2
Individual2	population1	locus1	allele1	 allele2

example

  • data for 15 individuals from two populations, genotyped for two loci:
    ind1    pop1    locA    194     198
    ind2    pop1    locA    198     198
    ind3    pop1    locA    192     198
    ind4    pop1    locA    190     198
    ind5    pop1    locA    190     194
    ind6    pop1    locA    194     198
    ind7    pop1    locA    190     198
    ind8    pop1    locA    184     190
    ind9    pop1    locA    190     192
    ind10   pop1    locA    184     192
