Formats

input files

"Populations" accepts file from other population genetic softwares:

- Génétix

and it has its own format:
"Populations" format allows to use unlimited number of alleles, of haploids, diploids or nploids. The format is close to Genepop but alleles at a given locus are separated by ":". Thus, man can code alleles with all ASCII characters.

Diploid population example:

"Grape populations in southern France"
ADHLocus1
ADH#2
ADHthree
ADH-4
ADH-5

Structured population

To code metapopulations, you can choose either "Genepop" or "Populations" format. You only need to give the name of population after the keyword "POP " (separator = "/")

exemple de populations structurées
locus1
locus2
locus3
POP Rennes/immeuble_sud/pop_3emeetage
ind1, (description des individus)
ind2, ...
ind3, ...
ind4, ...
POP Rennes/immeuble_sud/pop_2emeetage
ind1, (description des individus)
ind2, ...
ind3, ...
ind4, ...

Output files

Populations is able to produce various population genetic software formats:

Génétix

Populations

Lea

Immanc

microsat

Admix (G. Bertorelle)

Fstat (Jerome Goudet)

Phylogenetic trees are coded using the "Phylip" format. " Treeview" can be used for Windows or Linux, and you can use ">Treeplot" to convert the phylip format into postscript, adobe illustrator, gif... with colors for each populations

Matrix distances files are "Excel (gnumeric compatible)", "Phylip", "xgobi", "NTsys" or any text editor compliant.

Command line

You can use "Populations" as a command line programm (very useful for batch treatment) to infer phylogenetic trees:

populations name_of_input_file -"arguments"

Available arguments:

-phylogeny ind ou pop (default) for phylogenetic trees based on individuals or populations

-dist method (default: Nei standard, Ds) you can choose among: DAS, Dm, Ds, Dc, Da, dmu2, Fst, Cp, Dr, ASD, Dsw, Dr, Dru, Drw, Drl. see distances for details.

-construct method (default: upgma) possibilities upgma or nj (Neighbor Joining)

-bootstrap_ind number to indicate the number of bootstraps to perform on individuals

-bootstrap_locus number to indicate the number of bootstraps to perform on loci

-output name_of_treeview_file to indicate the name of the tree file (phylip tree format)

-level number , structured populations allows to choose the structuration factor (in the example: town level is 1, building level is 2...).

populations toutc2.txt -phylogeny pop -dist Dm -bootstrap_locus 10000 -output toutc2_10000_Dm.tre

Commands can be write in a .bat file (for DOS) or a script file (for UNIX).
