There are many of these, but to give a concrete example: Pilibacter
Pilibacter is in GTDB and has both NCBI and GTDB taxonomies listed:
Yet Pilibacter does not appear in either the NCBI_vs_GTDB nor GTDB_vs_NCBI mapping spreadsheets.
Why is this? Is there some key piece of information I am missing?
Thank you for bringing this to our attention. We are double checking, but I believe this issue here is that taxa that are perfectly congruent between GTDB and NCBI are not listed. This is largely a historical issue as this file was originally used to give an indication of differences between the GTDB and NCBI taxonomies. I have flagged that we should include all taxa in these files starting with the next GTDB release.
