phylo.betadiversity - invalid command?

Hi,
The phylo.betadiversity command keeps returning ‘Invalid command. Valid commands are…’, even when I try running it as outlined in the tutorial with the files in PbdExample.zip. I’ve tried the Linux 64-bit executables for mothur 1.24 and 1.25, as well as the 64-bit Windows executables. Am I missing something obvious? Would it help if I compiled mothur from source?
Thanks.

Hi,
The command phylo.betadiversity is not part of mothur and never was. I have removed the page about it from the wiki, sorry for the confusion.
Kindly,
Sarah
