hello everyone
i am new user to beast and trying to build BSP from mtDNA.
My youngest sample was taken around 2020, and I was trying to get a BSP plot, so I put the date as 2020 (attachment, P-1) and built the BSP, but the BSP gave the date in the minus sign (attachment, P-2). This is because I put the date in 2020 instead of -2020 or something else. And is there any way I can increase the resolution of the time interval? For example, if the time interval on the X axis is 10K, can I down it to 3 or 5K?
(Note: MY ESS value is not good because i am not trying to parameterize yet.)
Thank you very much.
