Constrain all phylogenetic groups to be monophyletic

Make option: strict clock trees (uniform) (prset brlenspr=clock:uniform)

+
1,000,000 updates (e.g. cycles)

discard first 50,000 as burn-in
+
sample a total of 10,000 trees (say)
+
 
+
Then process output to get probabilities of each possible phylogenetic assignment of query sequence.
+
 
+
In MrBayes - if you run the program with the constraints of monophyletic groups -
+
you are forcing the query sequence _not_ to be part of these groups. So that won't work.
+
Instead, run it without the constraints and simply check how often the query sequence is
+
member of a partition that only contains one particular phylogenetic group as members
+
(at any phylognetic level, e.g. species, genus, family, order, etc).
+
Remember, MrBayes will output the probabililities of specific groups (or partitions) directly.
+
So you don't have to do anything with trees yourself.
