117 This tool takes as input a Nexus file (.nex), described here_, that should only contain a data block, without commands. If a command block exists in the file, it will be executed first, followed by the ones specified above.

123 **What it does**
|
|
|
124
|
|
|
125 MrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models. MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters.

134 **Model Definitions**
|
|
|
135
|
|
|
136 Models are defined by the following MrBayes options::
|
|
|
137
|
|
|
138 GRT: lset nst=6;
|
|
|
139 SYM: lset nst=6; prset statefreqpr=fixed(equal);
|
|
|
140 HKY: lset nst=2;
|
|
|
141 K2P: lset nst=2; prset statefreqpr=fixed(equal);
|
|
|
142 F81: lset nst=1;
|
|
|
143 JC: lset nst=1; prset statefreqpr=fixed(equal);
|
|
|
144 Mixed: lset nst=mixed;
|
|
|
145
|
|
|
146 Each model makes different assumptions about nucelotide substitution rates and state frequencies.
|
|
|
147
|
|
|
148 The mixed model performs Markov chain sampling over the space of all possible reversible substitution models, by grouping the six rates in various combinations.

154 **Tip for repetitive analyses**
|
|
|
155
|
|
|
156 Note that running the same analysis on the same dataset in Galaxy will overwrite .p, .t, and .mcmc files for that dataset. This can be avoided by copying the dataset or re-uploading it, or by specifying a new filename.

160 **Tip for using append**
|
|
3
|
161
|
|
4
|
162 If you want to use the append functionality, all parameters will have to be identical to your initial analysis. The easiest way to ensure this is by using the blue "Run this job again" arrow on the dataset, and checking the additional append box. Note also that ngen will be the total number of generations, not the number of generations to add, so you should increase this value except if a run was interrupted. Selecting append while checkfreq > ngen will have no effect.
