====== FastTree ======

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. For large alignments, FastTree is 100-1,000 times faster than PhyML 3.0 or RAxML 7.

===== Information =====

  * Version: 2.1.11
  * Added: May, 2020
  * Link: http://www.microbesonline.org/fasttree/
  
===== Usage =====

See which versions of fasttree are available:
<code>$ module avail fasttree</code>

Load one version into your environment and run it:
<code>$ module load fasttree/2.1.11
$ FastTree</code>

*Note:* if you're using the multi-threaded ''FastTreeMP'' please specify the number of CPU threads to use with the ''OMP_NUM_THREADS'' environment variable:

<code>$ export OMP_NUM_THREADS=3
$ FastTreeMP</code>

The number of CPU threads you choose should match the number of CPUs requested in your SLURM SBATCH allocation.
