Hello 
qiime diversity core-metrics --i-phylogeny ok76_rooted-tree.qza --i-table ok76_table.qza --p-sampling-depth 12600 --output-dir ok_76_core-metrics-results
Error: no such option: --i-phylogeny
What an I missing??
Hi @Adi --- as of QIIME 2 2017.9, there are now two related methods for computing core metrics: core-metrics and core-metrics-phylogenetic - as their names suggest, one is related to phylogenetic metrics, the other isn't. You should be able to update your command to use core-metrics-phylogenetic, instead!
Hope that helps!
