Can someone help educating me on num_date feature on augur? After some research i found this date comes from the branch-lengths.json file. but how is this date generated/obtained? My data is from 2017. but here node 1 is 1978! is there any way to display the tree in a better way as in the nodes and the data points would be scaled properly? thanks!
Dates typically come from running augur refine (example). While dates for tips come from the provided sequence metadata (e.g. your 2017 data), the dates of internal nodes, including the root (what you mean by node 1?), are inferred by TreeTime during augur refine.
If you want to better focus on your data, try selecting it with a Filter and then enabling “Focus on selected”.
