Genesis produces structure charts by taking input from the Structure, Admixture or CLUMPP tools, together with a PLINK-style fam and optionally a phenotype file which would contain population labels.
To input these files, click File -> New Admixture
or the New Admixture
button on the toolbar. On the screen that opens, click Import Data File
and navigate to the admixture data file outputted by the Admixture/CLUMPP tools. Then click Import Fam File
and navigate to the fam data file. Finally, click Import Pheno File
and navigate to the phenotype data file.
You can import multiple data files into the same project by clicking Import Data File
again. These files can be imported in any order relative to the importing of the fam and pheno file.
In the drop-down menu select the column of the phenotype file that will be used to group the data. To draw the graph, click Finish
or click Next
to access the Appearance Options menu (See below...).
If a graph has already been plotted, and you wish to change the column of the phenotype data used to group the data or import additional data files, you can access the initial menu by clicking the Data Options
button on the toolbar, or clicking Graph -> Data Options
.
The Appearance Options menu can be accessed through the New Admixture
button by clicking Next
after importing the files or by clicking the Appearance Options
button on the toolbar, or clicking Graph -> Appearance Options
.

To select an individual subject on the structure plot, click on the subject on the plot. This will bring up a subject menu where you can view the data about the subject (from the phenotype data file) and gives the option to hide the subject from the plot.
To select a population group, click on the population group label for the group. This will bring up a menu where you can change the Name of the group and also shift the group left/right (or up/down) in the graph.
To change the colours and order of the colours in the graph, right click anywhere on the graph and select Population Group Options

To hide a subject from the graph, click on the subject on the graph to bring up the subject dialog. From this menu you can choose to hide the subject from the graph.
To hide a population group from the graph, click on the group in the key to bring up the population group dialog and check the box labelled Hide this group from the graph
.
To reshow a subject that has been hidden, click on the Select Hidden Individuals or Groups
