My yDNA test results are: SNP = R-M207 and STR = Q-M242. I'd be interested in comments or analysis. thanks

SNPs are more reliable than STRs for haplogroup designation, as SNPs serve as confirmation, whereas STRs only serve as prediction. What company did you test with?

SNP FROM CRI AND STR FROM FAMILY TREE DNA.

Are you able to download the raw data from CRI and analyse it yourself?

Also, have you ran your FTDNA STR's with NEVGEN? If so, would you be happy to provide a screenshot of the results? Here's mine as an example:

I don't think CRI will give me the raw data. I haven't used NEVGEN but will try. thanks

I just used NEVGEn and it gave me very different results with a 32% probability and 34% Fitness. I just talked with FTDNA and they are going to take a look at my results again.

I've done a little bit of research and CRI apparently do not accept raw data downloads, which is a shame.

Regarding FTDNA, an Anthrogenica user here has purchased FTDNA tests for men from her village and initially, their STR's couldn't be allocated reliably to a haplogroup, so FTDNA had to do what's called a backbone test, where they will test for a relatively small number of important mutations until they get a result (you won't get a very detailed result from this as it's free when they do it). This may be what FTDNA does for you. In any case, it's good that you contacted them.
