@Jeff - Agreed. Determining if the SNP is in the derived state, or not seems confusing. I am going to have re-confirm my manually looked-up classifications as to whether they are derived, or non-mutated.
Why wouldn't they just say, "non-mutated" instead of "common on affy axiom data?"
Those R1b1 classifications may be the same depending on the source. I've gotten thrown off a few times by seeing updated classifications, and subclades.
