*REQ* is a program for quickly estimating a confidence value at each branch of a distance-based phylogenetic tree. Branch support assessment is commonly based on bootstrap procedures [@felsenstein1985; @makarenkov2010; @lemoine2018]. Unfortunately, as they are based on numerous resampling of aligned characters, such procedures require long running times, despite some recent advances [@minh2013; @hoang2018a; @hoang2018b]. In fact, direct branch support methods were already developed for character-based approaches that optimize maximum-parsimony or maximum-likelihood criteria, in order to achieve faster running times [@bremer1988; @bremer1994; @anisimova2006; @anisimova2011]. However, to our knowledge, no practical implementation of direct branch support methods is currently available for distance-based approaches.
Distance-based approaches proceed in two steps: a pairwise evolutionary distance is estimated between each pair of (biological) objects, and, next, an algorithm is used to infer the tree with branch lengths that best fits the evolutionary distance matrix [@pardi2016]. Because of their speed, distance-based methods are widely used for inferring phylogenetic trees. Moreover, as such algorithms only need a distance matrix, they allow phylogenetic analyses to be carried out from a wide range of data types, e.g. DNA-DNA hybridization experiments [krajewski1990], gene orders [@wang2006; @house2014], gene content [@spencer2007], or unaligned genome sequences [@chapus2005; @henz2005; @cohen2012; @garcia2018]. Nevertheless, in such cases, standard bootstrap-based methods can not be used for estimating branch confidence values.

Nevertheless, in such cases, standard bootstrap-based methods can not be used for estimating branch confidence values.
In order to fill this void, the program *REQ* was developed. This tool estimates the rate of elementary quartets (REQ) for each branch of a given phylogenetic tree from the associated distance matrix, as described by [@guenoche2001]. This method simply computes the proportion of four-leaf subtrees (i.e. quartets) induced by every internal branch that are supported by the four-point condition applied to the six corresponding pairwise evolutionary distances [@zaretskii1965; @buneman1971]. Therefore, this measure is not based on a random sampling (such as bootstrap-based confidence supports). The closer this measure is to 1, the more the corresponding branch is fully supported by the pairwise evolutionary distances.
