When I create my taxa collapsed genus table I get a lot of blanks at the genus level, which I understand is not unusual. For example:
However, when I use this table to create LEfSe plots the blanks still show up. Is there a way to add “unclassified” to blank genus assignment in QIIME2? I am using QIIME2018.8 on a cluster, which is the only version available on the cluster.
