Hi @yxa,
I just wanted to extend @gregcaporaso's comment, with a few additional options:
-
Use qiime rescript edit-taxonomy ... to remove everything but the genus ranks. You can enable the
--p-use-regex
flag to make this easier. Then you can feed this output into thedokdo prepare-lefse ...
command -
Or after you run
dokdo prepare-lefse...
, open the resulting text file. You'll see that LEfSe delimits that taxonomic ranks with a|
character. You can simply find and replace all of the|
with.
or_
characters so that that taxonomy is simply one long string. You can feed this into LEfSe for analyses. Note the taxonomic cladogram will not be informative, as it'll look like a "star" w/o hierarchy. Or remove as many of these delimiters you'd like up to the rank you want to focus on, then run LEfSe.
