I am currently trying to filter select taxa (e.g., archaea) from my table, and I am running into the following error:
"Plugin error from taxa:
CategoricalMetadataColumn does not support values with leading or trailing whitespace characters. Column ‘Taxon’ has the following value: 'D_0__Bacteria;D_1__Armatimonadetes;D_2__uncultured;D_3__uncultured bacterium '"
From reading the previous forums, its advised to either delete whitespaces manually [this did not work] or using a transformer https://github.com/qiime2/q2-types/issues/179 should work. How would one go about using the transformer?
