%description
A tool that implements the clustering algorithms from 'mothur' (Schloss PD
et al. (2009) <doi:10.1128/AEM.01541-09>). 'clustur' make use of the
cluster() and make.shared() command from 'mothur'. Our cluster() function
has five different algorithms implemented: 'OptiClust', 'furthest',
'nearest', 'average', and 'weighted'. 'OptiClust' is an optimized
clustering method for Operational Taxonomic Units, and you can learn more
here, (Westcott SL, Schloss PD (2017)
<doi:10.1128/mspheredirect.00073-17>). The make.shared() command is always
applied at the end of the clustering command. This functionality allows us
to generate and create clustering and abundance data efficiently.
