part of mauveAligner package reads all trees and their posterior from a set of MrBayes .trprobs files

## NAME

extractBCITrees - part of mauveAligner package reads all trees and their posterior from a set of MrBayes .trprobs files

## SYNOPSIS

**extractBCITrees** *\<random seed\> \<BCI threshold\> \<max output trees\> \<MrBayes .trprobs input file 1* .. *N\> \<nexus output file\>*

## DESCRIPTION

This program reads all trees and their posterior from a set of MrBayes .trprobs files and sums and normalizes posteriors for each topology.  All trees that meet a Bayes Credible Interval threshold will be saved, up to some maximum number of trees. \<BCI Threshold\> A number between 0 and 1 giving the BCI threshold.  0.9 is a good choice. \<max output trees\>      Limit the output to this many trees. All trees in the input file must have the same number of taxa and the same taxon labels
