Fast phylogenetic tree building of huge datasets
Requires Geneious 7.0+
FastTree infers approximately-maximum-likelihood phylogenetic trees from alignments of nucleotide or protein sequences. FastTree can handle alignments with up to a million of sequences in a reasonable amount of time and memory.
Install the plugin by downloading the gplugin file and dragging it in to Geneious or use the plugin manager in Geneious (under Tools - Plugins in the menu).
Once installed, run the plugin by selecting a multiple sequence alignment and clicking on Tree in the toolbar. FastTree is available as an option at the top of the Tree building options window.
