I posted this in Getting Started a while ago but it seems like General is the topic that actually gets traffic. It’s my understanding that ancestral reconstruction is done with maximum likelihood methods, I can see there’s an option of joint or marginal for augur ancestral. Is this also the case for augur traits? i.e. can I run reconstruction with marginal likelihood for augur traits?
