1. Why is my project not listed in the project selector dropdown?
    • No one has submitted data for your project to PhyloGeographer or the data hasn't yet been validated and added to the dropdown, which can take a few days.
  2. Where does the data come from?
    • Each haplogroup project available in the project selector has been submitted by a contributor. Generally they are haplogroup administrators that have access to many individuals' tests within the same haplogroup.
    • For information about the data used in your project and notes from the contributor that submitted it, see the Projects page (in construction).
  3. How can I add my haplogroup project to PhyloGeographer?
    • If you have access to your project's kit data and understand your tree, follow the instructions for Create a New Project.
    • If you do not have access to the data, ask your haplogroup administrator or co-administrator to publish your project to PhyloGeographer.
  4. How can I generate my Cultural Ancestry Report?
    • This is currently in development. I am looking for volunteers to help add to the database of archaeological horizons. To contribute, please join the Facebook group.
  5. Why is the tree missing a clade(s)?
    • If you think there may be an error in your tree, please contact the publisher (most likely your haplogroup administrator) to make them aware of it.
  6. Who determines the SNPs used to define the clades on PhyloGeographer?
    • The publisher who submitted data for the haplogroup decides the SNPs used to define the clades. They can at any time update the tree to use new SNPs, add new branches or kit data.
  7. Why are some clades computed to have originated in bodies of water?
    • In Version 1.0 and 2.0 the method for determining a clade's origin does not take bodies of water into account. It averages latitudes and longitudes of points. For details see Methodology.
    • If your project contains kits with latitudes and longitudes in the Americas and also in Europe, the clades will probably be computed to have formed in the Atlantic Ocean. To avoid this behavior and obtain a more accurate result, use the kits surname to infer a likely paternal origin and use this country / region's location instead. If a country of origin cannot be determined, remove the kit from the data set because it is obscuring results.
  8. Someone in my genetics forum has cited PhyloGeographer's analysis as evidence to prove their point. How reliable are the computed clades?Before citing an analysis from one of our projects as part of your argument in a genetic forum please understand:
    • The larger the circle in clade origin mode, the greater the average distance from computed clade origin to the children. This can signify unreliability that may be resolved with the discovery of a future SNP that splits the clade.
    • If the sampling of your project biases particular regions, the results are inherently unreliable. For example there will be some bias toward Sardinia and populous areas in Europe such as the "Blue Banana" where population density is higher and people have more disposable income to engage in genetic testing
    • Clades with no children or those computed from only a handful of kits are unreliable. Uncertainty from these factors is not yet visually represented.
    • I think PhyloGeographer is valuable for helping any project member identify emerging, previously unidentified patterns as tests accumulate and our knowledge of trees diversifies. Any insight from this tool  should however be taken into context with the opinion of your haplogroup administrator who may be the only person experienced enough to fully appreciate the confounding factors outlined above.
