..Info for Big Y Users

The report lists what are called "novel variants."  These are merely results different from the reference sample.  
Some are items that have become known since they selected items to test, and these now have names.
Many others are items that show up in a person as a mutation, but when compared to the results from other
men will be shown to be from sites that frequently mutate and are thus useless.  There is no way to distinguish
good "novel variants" from bad ones without assistance from someone who works with raw data from Y-DNA
sequencing samples frequently or pay a company that can do this analysis.

In general the 22 million section tends to have unusual numbers of useless positive results.
Items reported in the 25, 26, 27 million sections have usually not proven useful.
