TreeBeST: Tree Building guided by Species Tree (Ensembl Compara modifications)
This repository holds the necessary changes of Heng Li's version to run the latest Ensembl Compara pipeline.
You can find more documentation on SourceForge: (http://treesoft.sourceforge.net/treebest.shtml)
The main new features are:
treebest sdi, to allow a user-defined species tree. This change is from Albert Vilella
Tnode-tag in the NHX output: a bit-field listing the input trees that support the node. This is populated by the mmerge algorithm
treebest nj, to carry on the
Ttags from the input tree
treebest best, to redefine the PhyML variable
MIN_DIFF_LK. It prevents PhyML from crashing during its computation
treebest best, to give a higher weight to the likelihood that comes from the reconciliation with the species tree (default 1)
- Species-intersection scores are now also reported as floating-point values under the
DCSnode-tag. The value is between 0 and 1, and displayed with 4 decimals.
treebest best, to start from the input tree instead of building one
Other changes include:
- bugfixes / tweaks when processing the filtered alignments (TreeBeST includes a Clustal-score-based MSA-filtering step)
- bugfixes / tweaks when merging the trees
floatfor floating-point values
