Hi @Talingar, Welcome to the :qiime2: forum. You may want to look at why your reference library didn't work so well, or try a different techique for assignment. (Others are probably better equiped to help with that, Ive not done COI). However, you could export your taxonomy.qza artifact to a text file (see the [exporting data page](https://docs.qiime2.org/2020.2/tutorials/exporting/)), use [qiime2R](https://forum.qiime2.org/t/tutorial-integrating-qiime2-and-r-for-data-visualization-and-analysis-using-qiime2r/4121) to import it into R or use the [python API](https://docs.qiime2.org/2020.2/interfaces/artifact-api/) to pull it into python and make your edits there. (My personal recommendation is python or R because then you have a better record of what got changed where and why and how.) If you go with the R or export solution, you then need to [re-import the updated taxonomy as an artifact](https://docs.qiime2.org/2020.2/tutorials/importing/).
