GTDB taxonomy taxdump files with trackable TaxIds

Metagenomic tools like Kraken2, Centrifuge and KMCP support NCBI taxonomy in format of NCBI taxdump files. GTDB, a prokaryotic genomes catalogue, has its own taxonomy data. Though the genomes, derived from GenBank and RefSeq, can be mappped to NCBI taxonomy TaxIds, there's an urgent need to create its own taxonomy taxdump files with stable and trackable TaxIds.

A TaxonKit command, taxonkit create-taxdump is used to create NCBI-style taxdump files for any taxonomy dataset, including GTDB and ICTV.

Method

Taxonomic hierarchy

A GTDB species cluster contains >=1 assemblies, each can be treated as a strain. So we can assign each assembly a TaxId with the rank of "no rank" below the species rank. Therefore, we can also track the changes of these assemblies via the TaxId later.

Generation of TaxIds

We just hash the rank+taxon_name (in lower case) of each taxon node to uint64 using xxhash and convert it to int32.

For the NCBI assembly accession.
1. The prefix GCA_ is not used because some GenBank entries (GCA_000176655.2 in R80) were moved to RefSeq (GCF_000176655.2 in R83) and the prefix changed.
2. The version number is trimed because it may change. So, 000176655 is hashed to get the TaxId.
For the non-NCBI assembly accession. The accession per se is hashed. E.g., UBA12275
For the name of a node. The taxon name per se is hashed. E.g, Bacteria.

Data and tools

GTDB taxnomy files are download from https://data.gtdb.ecogenomic.org/releases/, and organized as:

TaxonKit v0.12.0 or a later version is needed. v0.16.0 or a later version is preferred.

Since v0.14.0, taxonkit create-taxdump stores TaxIds in int32 following BLAST and DIAMOND, rather than uint32 in previous versions.
Since v0.16.0, duplicated names with different ranks are allowed.

Steps

Generating taxdump files for the first version r80:

 taxonkit create-taxdump taxonomy/R080/*.tsv* --gtdb --out-dir gtdb-taxdump/R080 --force
 22:23:09.195 [INFO] 94759 records saved to gtdb-taxdump/R080/taxid.map
 22:23:09.249 [INFO] 111705 records saved to gtdb-taxdump/R080/nodes.dmp
 22:23:09.293 [INFO] 111705 records saved to gtdb-taxdump/R080/names.dmp
 22:23:09.293 [INFO] 0 records saved to gtdb-taxdump/R080/merged.dmp
 22:23:09.293 [INFO] 0 records saved to gtdb-taxdump/R080/delnodes.dmp

For later versions, we need the taxdump files of the revious version to track merged and deleted nodes.

 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R080/ \
     taxonomy/R083/*.tsv*  --out-dir gtdb-taxdump/R083  --force
     
 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R083/ \
     taxonomy/R086/*.tsv*  --out-dir gtdb-taxdump/R086  --force

 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R086/ \
     taxonomy/R089/*.tsv*  --out-dir gtdb-taxdump/R089  --force
     
 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R089/ \
     taxonomy/R095/*.tsv*  --out-dir gtdb-taxdump/R095  --force
     
 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R095/ \
     taxonomy/R202/*.tsv*  --out-dir gtdb-taxdump/R202  --force
     
 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R202/ \
     taxonomy/R207/*.tsv*  --out-dir gtdb-taxdump/R207  --force

 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R207/ \
     taxonomy/R214/*.tsv*  --out-dir gtdb-taxdump/R214  --force

 taxonkit create-taxdump --gtdb -x gtdb-taxdump/R214/ \
     taxonomy/R220/*.tsv*  --out-dir gtdb-taxdump/R220  --force

Generating TaxId changelog (Note that, it's not perfect for GTDB taxonomy).

We only check and eliminate taxid collision within a single version of taxonomy data. Therefore, if you create taxid-changelog with "taxid-changelog", different taxons in multiple versions might have the same TaxIds and some change events might be wrong.

A single version of taxonomic data created by "taxonkit create-taxdump" has no problem, it's just the changelog might not be perfect.

    taxonkit taxid-changelog -i gtdb-taxdump -o gtdb-taxid-changelog.csv.gz --verbose

Download

The release page contains taxdump files for all GTDB versions, and a TaxId changelog file (gtdb-taxid-changelog.csv.gz).

TaxId changes

Notes:

The Y axis is the number of TaxId, not that of species.
The data is generated by "taxonkit taxid-changelog", which was originally designed for NCBI taxonomy, where the the TaxIds are stable. For other taxonomic data created by "taxonkit create-taxdump", e.g., GTDB-taxdump, some change events might be wrong, because
- There would be dramatic changes between the two versions.
- Different taxons in multiple versions might have the same TaxIds, because we only check and eliminate taxid collision within a single version

Taxon history of Escherichia coli

csvtk is used to help handle the results.

Get the TaxId:

$ echo Escherichia coli \
    | taxonkit name2taxid --data-dir gtdb-taxdump/R220/
Escherichia coli        599451526

Any changes in the past? Hmm, of cause, it appeared in R80.

$ zcat gtdb-taxid-changelog.csv.gz \
    | csvtk grep -f taxid -p 599451526 \
    | csvtk cut -f -lineage-taxids \
    | csvtk csv2md

In R214, the phylum Proteobacteria changed to Pseudomonadota, also mentioned in the release announcement.

And Escherichia coli absorbs four taxa in R207, let's see what happened to them:

$ zcat gtdb-taxid-changelog.csv.gz \
    | csvtk grep -f taxid -p 1223627963,1584917910,1670897256,2030830777 \

2030830777	R207	MERGE	599451526	Escherichia flexneri	species	Bacteria;Proteobacteria;Gammaproteobacteria;Enterobacterales;Enterobacteriaceae;Escherichia;Escherichia flexneri

Yes, Escherichia flexneri is merged into Escherichia coli as reported in the release note of R207.

We can also check the history of an Escherichia flexneri assembly. Listing assemblies:

$ taxonkit list --data-dir gtdb-taxdump/R202/ --ids 2030830777 -n -r -I "" \
    | head -n 5
2030830777 [species] Escherichia flexneri

530007 [no rank] 003981095
930852 [no rank] 005393725

E.g., the taxon node 013185635 (taxid 169219442). Let's check the history via the TaxId:

$ echo 013185635 | taxonkit  name2taxid --data-dir gtdb-taxdump/R202/
013185635       169219442

$ zcat gtdb-taxid-changelog.csv.gz \
    | csvtk grep -f taxid -p 169219442 \
    | csvtk cut -f -lineage-taxids \
    | csvtk csv2md

taxid	version	change	name	rank	lineage
169219442	R202	NEW	013185635	no rank	Bacteria;Proteobacteria;Gammaproteobacteria;Enterobacterales;Enterobacteriaceae;Escherichia;Escherichia flexneri;013185635

Note that we removed the prefix (GCA_ and GCF_) and version number (see method). So the original assembly accession should be GCA_013185635.X, which can be found in taxid.map file:

$ cat gtdb-taxdump/R214/taxid.map \
    | csvtk grep -Ht -f 2 -p 169219442
GCF_013185635.1 169219442

The GCA_013185635.1 page also shows the taxonomic information of current version (R207) and the taxon history:

Note: the TaxIds below may be not the lastest (taxonkit v0.14.0 save TaxIds in int32 instead of uint32).

Inaccurate delnodes.dmp and merged.dmp for a few taxa with same names

In old versions, some taxa had the same names, e.g., 1-14-0-10-36-11.

# r86.2

# taxid of 1-14-0-10-36-11: 810514457
GB_GCA_002762845.1	d__Archaea;p__Nanoarchaeota;c__Woesearchaeia;o__GW2011-AR9;f__GW2011-AR9;g__1-14-0-10-36-11;s__

Later in r89, the Archaea genus 1-14-0-10-36-11 was renamed, while taxid 3509163818 was assigned to Bacteria genus 1-14-0-10-36-11 and taxid 3509163819 was marked in delnodes.dmp.

# genus changed, and assigned a new species
GB_GCA_002762845.1	d__Archaea;p__Nanoarchaeota;c__Nanoarchaeia;o__Woesearchaeales;f__GW2011-AR9;g__PCYB01;s__PCYB01 sp002762845

# assigned a new species
# taxid of 1-14-0-10-36-11: 3509163818

As a result, the taxid-changelog showed:

Unstable delnodes.dmp and merged.dmp for a few taxa of which genomes are mreged into different taxa

An example: In R95, some (Sphingobium japonicum_A) genomes (GCF_000445085.1) were merged into (Sphingobium chinhatense), while others (GCF_000091125.1) into Sphingobium indicum. Check details

Merging GTDB and NCBI taxonomy

If you need the taxdump files and the taxid.map file mapping genome assembly accessions to TaxIds, please follow Merging the GTDB taxonomy (for prokaryotic genomes from GTDB) and NCBI taxonomy (for genomes from NCBI).
If you just need the taxdump files, please follow Merging GTDB and NCBI taxonomy.
