 The taxonomic assignments from PEMA for COI and 18S from the batch 1 processing of the ARMS-MBON data have been curated by us to accommodate some issues:
 *  Due to a bug in V2.1.4 of PEMA (subsequently fixed), the assignments in the **Extended_final_table_XX_.xlsx files for COI** in the [taxonomic_assignments folder](https://github.com/arms-mbon/data_workspace/tree/main/analysis_data/from_pema/processing_batch1/taxonomic_assignments) are only denoted to the genus level. The species-level assignments can be found in the tax_assignments files that accompany those final tables. We have extracted those species-level assignments and inserted those, together with newly-minted species-level NBCI IDs, into new Extended_final_table files. The code to do this and the new tables can be found here.
 *  For the **Extended_final_table_XX_.xlsx files for 18S**, the taxonomy returned from the PR2 database is not as straightforward to compare to taxonomies from other databases due to its unique organisation of taxon nodes used. In order to make more sensible use of these taxonomy results for our subsequent need to match the taxonomic assigments to WoRMS (World Register of Marine Species), we have undertaken a curation of the taxonomic classification for 18S. The code for doing this curation, and the outputs from the curation (being new Extended_final_table files and new taxonomic assignment files) can be found here. It is up to the user to decide whether they wish to adopt these curations for their own work, or not. For the specific case of 18S taxonomy, strings assigned by the PR2 database were curated as follows:
