The directory _example_ contains two files from the study of [Garcia-Hermoso et al. (2018)](https://doi.org/10.1128/mBio.00573-18):
* _matrix.d_: a distance matrix in PHYLIP square format estimated from 22 _Mucor circinelloides_ f. _circinelloides_ genomes,
* _tree.t_: the associated Minimum Evolution phylogenetic tree in NEWICK format.
* _tree.t_: the associated minimum-evolution phylogenetic tree in NEWICK format.
The following command line writes into the file _tree.req.t_ the phylogenetic tree from _example/tree.t_ with the rate of elementary quartets at each internal branch estimated from the distance matrix _example/matrix.d_:
```bash
REQ example/matrix.d example/tree.t tree.req.t
REQ example/matrix.d example/tree.t tree.req.t-v
```
Because the option -v is set, the verbose mode will output the tree topology in NEWICK format, the list of leaf names, and, for each internal branch, the leaf quadripartition together with the rate of elementary quartets _Re_:
tr=tr.insert(0,'(');sup=apc(tr,tr.lastIndexOf(")"));tr=tr.insert(sup,')');//# NOTE: closing parenthesis at index 'sup' should not be considered for REQ calculations
