Silent and inconsistent behaviour selecting unlinked Tree Prior #421

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
If a tree prior is selected over multiple unlinked trees then for most models a 
separate coalescent likelihood is generated for each tree with a shared 
coalescent model. For ESB however a multi locus model is generated. Perhaps it 
would be more transparent to have a multi locus check box that is only enabled 
by those models that allow multilocus behaviour and if it is off then it uses 
the default behaviour. There is currently no UI element that indicates that 
multilocus will be used.

This is not inconsistent. For the simple population models (constant, 
exponential, et cetera) producing a separate coalescentLikelihood for each tree 
with a linked DemographicModel *is* a multi-locus analysis. It just looks 
different to EBSP in the XML. We could add a message into the user interface 
that says "Multi-locus coalescent analysis" whenever multiple unlinked trees 
are given the same tree prior. Would that help?
