Note that because admixture estimation is expensive computationally, the Gedmatch.com tools are slightly less accurate than DIYDodecad because of more lax termination criteria. This should not be a problem for the major components of one's ancestry, but may be for the minor ones. Moreover, convergence is achieved with a different number of iterations for different genotype files, so accuracy may vary.
Two other genome bloggers have released their own calculators that can be run with DIYDodecad. Magnus Ducatus Lituaniae has released MDLP based on its K=7 analysis. Eurogenes has released a K=14 imaginatively named test calculator for Eurasian data.
I keep a list of calculators for DIYDodecad in the DIYDodecad 2.0 page.
I neither endorse nor am I affiliated with any third-party tools, but I encourage readers to try them out; the more the merrier.
