Fixing a starting tree on SNAPP

[Prahalad S be18b036]

Hey everyone,

I am working on estimating divergence times between different populations of the same species using SNAPP.

I had initialised a tree and tried following the same method as this post but I am getting a different error and am not sure how to proceed.

I have attached the drive link with the beast and xml files below. Any help would be greatly appreciated. Thanks in advance
