Overview

Each quarter EcoliWiki incorporates the E. coli annotations from EcoCyc into our website. Upon each EcoCyc release the annotations are parsed and loaded into the wiki using automated scripts.

Known Issues

• Currently EcoliWiki has not been removing annotations that were removed from EcoCyc.

Detailed Description

IEA Collapsing

• In order to keep the number of computational annotations rows down to a manageable level (and so they don't overwhelm the tables) EcoliWiki "collapses" these rows. This means computational annotations for any particular product that are assigned to the same GO term will be collapsed into one row.

An example, these rows are from a gene_associations.ecocyc file that was imported:

EcoCyc  EG10240-MONOMER DnaJ            GO:0051082      GOA:hamap|GO_REF:0000020        IEA     HAMAP:MF_01152  F       chaperone with DnaK; heat shock protein dnaJ|groP|grpC|b0015|ECK0015    protein taxon:511145    20091214        UniProtKB

Notice that these 5 annotations are assigned to only 2 GO terms. After processing (and formatting for EcoliWiki), they look like this:
