The colorization system was inspired by Jason Clary who devised a scheme to make observations of the differences between samples easy and efficient. He graciously supplied Family Tree DNA his colorization code which was modified in house to support our sub grouping system.
Family Tree DNA thanks Jason for the time he spent pioneering this system for the benefit of our group administrators and project members.
How to make the colorization system work for your project:
1. You must use the Family Tree DNA sub-grouping system to ‘turn on’ Colorization.
2. Instructions for using the sub-grouping system can be found here.
3. Individuals cannot be in more than one sub-group.
4. The system will automatically define and color the background of markers that appear as mutations from the modal, or most common, set of marker values for that sub-group.
5. A blue background means that the marker value is lower (-) than the modal while a red background means the value is higher (+) than the modal.
6. The darker the color, the greater the genetic distance between an individual and the modal (most common) marker value for the group.
7. Hold your mouse over a colorized marker to display the distance from the modal value.
8. There is a sigma symbol above each of your subgroups. The calculated the sub-groups minimum, mode, median, mean and maximum value for each sub-group. Click on the link for each to see a definition of these terms.
9. Members who are not in a sub-group will appear at the bottom of the page display and will not be colored.
10. NULL marker values (primarily DYS 439) remain in dark blue & bold font and are not colorized.
