The calculator combines data from Henn et al. (2011), HGDP, and Behar et al. (2010). As a result, the number of SNPs is small: there is probably noise in the minor components, but the major components of one's ancestry should be well-defined.
It should be used only by Africans and African-West Eurasian admixed individuals. It is not meant for people with additional admixture (e.g., South/East Asian or Native American).
You need to extract the contents of the RAR file to the working directory of DIYDodecad. You use it by following exactly the instructions of the DIYDodecad README, but always type 'africa9' instead of 'dv3' in these instructions.
NB: Note that the components of 'africa9' do not necessarily have the same meaning as the same-named components you might have seen elsewhere. Refer to the spreadsheet for the admixture proportions and Fst distances between components. For example, the NW African is substantially removed from other West Eurasian components in Dodecad v3 but equidistant from Europe and SW_Asia in 'africa9'. I also advise that you read Interpretation of ADMIXTURE results: component sharing
