Estimates of the clock and TMRCA for 2019-nCoV based on 27 genomes.
Kristian Andersen, Scripps Research
Following up on the analyses provided by Andrew Rambaut this is a brief report estimating the evolutionary rate and timing of the epidemic (date of the most recent ancestor (MRCA)) based on 27 publicly shared n2019-nCoV genome sequences. Compared to earlier analyses where several parameters had to be fixed, there is now enough information content in the sequences to obtain reasonable estimates of the clock and TMRCA without fixing parameters. This work is for information purposes only and is not intended for publication. All the data used here is provided by the laboratories listed below through NCBI Genbank or GISAID.
