Tracking Human Population History: The Role of MSMC and MSMC2 1. Introduction
MSMC is a Hidden Markov Model (HMM) that utilizes the density of (genotypes where alleles differ) to estimate the time to the most recent common ancestor (TMRCA). Download MSMC Maps from Here (Click on this text)
) : The primary purpose of MSMC is to estimate the inverse of the coalescence rate, which can be interpreted as the Necap N sub e over time.
: Recent applications have detected traces of ancestry dating back over a million years in certain African populations. 4. Practical Implementation : Execute the software to estimate coalescence rates
: The model requires several input files, typically one per chromosome, containing segregating sites and information on "called" sites.
MSMC and its successors remain vital tools for genomic research, providing a high-resolution view of human diversification. By modeling the drift and migration of our ancestors, these tools help clarify the demographic processes at the root of major historical transitions. ) : The primary purpose of MSMC is
: Because MSMC needs to know which regions of the genome could actually be called (filtering for quality and coverage), users must provide a Mask-file to exclude unreliable data.
