MCMCTree 分析中的時間單位問題——100百萬年

先見教程：http://abacus.gene.ucl.ac.uk/software/MCMCtree.Tutorials.pdf

The tree file looks like this
71
((((human, (chimpanzee, bonobo)) '>.06<.08', gorilla), (orangutan, sumatran)) '>.12<.16', gibbon);
//end of file
((((human, (chimpanzee, bonobo)) 'B(.06, .08)', gorilla), (orangutan, sumatran)) 'B(.12, .16)', gibbon);
The first line has the number of species (7) and the number of trees (1). Then the tree in Newick format is given. The tree must not have branch lengths. The tree has two fossil calibrations, one for the most recent common ancestor of human-chimp: ’> .06 < .08’ and another for the most recent common ancestor of the greater apes: ’> .12 < .16’. The time unit is 100 Million years (Myr). So the first calibration restricts the common ancestor of human-chimp to be between 6-8 Myr ago.

由原文程序設(shè)定可知，分子鐘的時間單位是100 Million years (Myr)，所以在運(yùn)行MCMCTree分析時輸入的時間校正單位也應(yīng)該是100百萬年
