Map Gi Numbers To Go Codes

Question

[kajendiran56]

Dear All, thank you for taking the time to view my post. I was wondering if there are any mapped files available that contain all the GO codes associated with a given NCBI gi number? Many thanks for your time

[jingtao09]

look here: ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/gene2go.gz and the REAME about it: """

gene2go recalculated daily

       This file reports the GO terms that have been associated
        with Genes in Entrez Gene.
       It is generated by processing the gene_association files
        on the GO ftp site: 
        <http://www.geneontology.org/GO.current.annotations.shtml>
       and comparing the DB_Object_ID to annotation in Gene,
       as also reported in gene_info.gz .....

""" If you really want to have that "table", I guess you need find "gene2gi" table which is a multiple to multiple relationship database. Or you can refer the work done by blast2go.org

Have a look at the SwissProt flatfile. It contains both GO(s) and GI for a given protein.

Please add a link to the file / data.

Thank you, yes this is true however, this only appears to be true for the annotated database. This does seem to be the best I can find in terms of a flat file.

Jingtao09 seems to have an interesting solution. I will look into this.
