Prediction of Y-chromosome haplogroup from Y-STR values is easy and fast with this program. You may choose a version of the program with the markers in FTDNA order or numerical order by clicking the button of your choice above. First time users should read the Instructions page first (see tabs above). Some companies use different standards for some markers, so read the "Conventions" page (see tabs above) to see which standards (nomenclature) are used in this program. Markers for which there are nomenclature issues are colored pink on the data entry page. An example of the data entry screen is shown below.
There are links on the right to two articles describing the "fitness score" calculations and the Bayesian probability calculations.
