EggNOG database introduction

 EggNOG is a database of orthologous groups and functional annotation.EggNOG (v4.5) currently covers 2,031 species, covering 1,678 bacteria,115 archaea, 238 eukaryotic species and 352 viruses.About 190,000 direct homologous clusters, consisting of 25 broad classes, were constructed.


Input files


Fasta file of nucleic acid or amino acid query sequences.

Results

1. Mapping and annotation results

2. Statistics of alignment

3. Distribution of E-values.

example


1. Mapping and annotation results


Query_id :ID of query sequences

Query_length:length of query sequsences

Query_start :the start position of query sequences covered by alignment

Query _end :the end position of query sequences covered by alignment


Subject_id :ID of mapped sequences in database

Subject_length:length of subject sequsences

Subject_start:the start position of subject sequences covered by alignment

Subject_end:the end position of subject sequences covered by alignment

Identity(%) :identity of alignment (percentity)



Gap:number of gaps

Align_length:the length of sequences covered by alignment

Score:Score of alignment, the higher the better


E_value :Expcet values of alignment, the lower the better

Subject_annotation:the annotation  of function

NOG-ID:The ID of eggNOG


description :the description of function

Class :the categories of functional





2. Statistics of alignment

showing the number of mapped and unmapped results.

3. Distribution of E-values.

E value is the expected value of the alignment. The smaller the E value, the more the reliability. We divided the E value into five ranges and show the number with a pie chart.
