DICE is a program to infer nuclear contamination from present-day humans in ancient DNA datasets using a Bayesian Markov Chain Monte-Carlo (MCMC). It also co-infers the demography and determines the most likely contamination source.

DICE works by computing the likelihood of finding a certain derived allele as contaminant by using the derived allele frequency in a potentially contaminating population. It is also possible that this derived allele is found endogenously in the sample. Given drift parameters, we compute the probability of observing the 3 following genotypes:

(ancestral , ancestral)
(derived , ancestral)
(derived , derived)

given the derived allele frequency in an anchor population. Since both the contamination rate and the demographic parameters depend on each other, we jointly infer them.

Is this supposed to be an announcement for DICE or a question about DICE? I don't see any links for the program, if former.

A tool announcement, sorry forgot the link to the paper and software. Adding it now, thanks!!
