question about the ACRY07 branch relaxer model

[tamsen]

Hi there,

I wanted to test SaGePhy branch relaxer in comparison to the original BRANCHRELAXER from (Sjo ̈ strand et al. 2013), for the autocorrelated lognormal model of Rannala and Yang (2007). If the BRANCHRELAXER settings I have are for a mean of 1 and drift distributed as Gamma(1, 1,000), such that drift had a mean of 0.001 and variance of 1e10^-6 (as in Tiley 2019), what settings would I need in SaGePhy to run the equivalent model? The sageph manual says ACRY07 [start rate] [σ 2 ]... so should my settings be [1] and [1e10^-6] ...?

Thank you,
Tamsen
