The file "uniprot-XX-XXXX-XXXX.tsv.gz" contains mappings from Uniprot Accessions
to EggNOG Orthologous Groups (OGs) in 4 taxonomic levels: LUCA, Bacteria,
Eukaryotes, Archaea.

ABOUT THE MAIN FILE CONTENT
===============================


- Each row represents a Uniprot Accession 
- Columns are tab delimited. 
- Columns 2, 3, 4 and 5 provide the list of OGs where the protein exist at 4
  taxonomic levels.
- Empty fields are expected if no OGs are available from a taxonomic level. 
- If a protein exists in more than one OG (i.e. due to gene
  fusions), several OG names will be separated by commas.
- If a protein does not belong to ANY known orthologous group, columns 2, 3, 4 and
  5 will be filled with a dash.

NOTE: 
=======
Four separate files are also provided for each taxnomic level. Those file do
only contain Uniprot Accessions with a match in EggNOG. Files are two columns
tab-delimited files. Multi-group matching is expected for some entries. In that
cases, matching groups are separated by commas in the second column. 


EggNOG linking
======================

- You can link to the default EggNOG view for a given protein id by using: 

http://eggnogdb.embl.de/#/app/results?seqid=[UniprotAccession]

- To find protein in a specific OG, use: 

http://eggnogdb.embl.de/#/app/results?seqid=[UniprotAccession]&target_nogs=[NOGID]

Examples:

http://eggnogdb.embl.de/#/app/results?seqid=C4G8M3
http://eggnogdb.embl.de/#/app/results?seqid=C4G8M3&target_nogs=ENOG4105F9F
http://eggnogdb.embl.de/#/app/results?seqid=Q4SR43&target_nogs=KOG1095
http://eggnogdb.embl.de/#/app/results?seqid=Q4SR43&target_nogs=COG0515

Note that LUCA is the default taxonomic level and contains sequences from the
three kingdoms (mappings to the original COG groups are included at this
level). However, more precise orthologs are provided if the taxonomic scope is
restricted to any of other 3 levels Bacteria, Eukaryota and Archaea.
