I’m trying to use the command “phylo.diversity” but I get this message of error:

“Name: 3801 is not in your groupfile, and will be disregarded.
Error: Missing branch length in input tree.”

I used my groupfile for other analyses and it worked fine. As for the input tree, I created it using the “dist.seqs” followed by the “clearcut” commands like so:

“mothur > dist.seqs(, output=lt, processors=2)
mothur > clearcut(”

Thank you in advance for your help!
