when particular clades diverged, or applying each I start by making three columns in Excel: taxon names, maximum age, and minimum age. I had a tree with lots of extant mammals and like 2 fossil taxa; to make the time-calibration make more sense, I needed some ages for deeper splits in the mammal tree, like the split between marsupials and placentals, the split between euarchontoglires and laurasiatheres, etc. The best way to format your data is therefore to set up an excel spreadsheet like this: if you have 10 taxa, rows 1-10 in excel are blank, and your first internal node is row 11. Then, do cal3 using the end points of those rates to assess

PAUP* 4.0 and MacClade 3 use a common data file format (NEXUS), allowing easy interchange of data between the two programs. To figure out the numbers for the internal nodes, you can use getMRCA.
