Phylo.diversity in mothur

I tried to use Phylo.diversity in mothur(Galaxy) to analysis alpha diversity of microbiology, but the galaxy(mothur) seems different from mothur. in mothur, it should be used command dist.seqs–clearcut-- Phylo.diversity, while in galaxy(mothur), I can not connect dist.seqs with clearcut. so can anyone help me about how to calculate Phylo.diversity by galaxy.
