DAVID Gene Accession Conversion Tool


   1. Introduction

This tool was built based on the "DAVID Gene Concept", a graph theory evidence-based method to agglomerate species-specific gene/protein identifiers the most popular resources including NCBI, PIR and Uniprot/SwissProt. It groups tens of millions of identifiers into 1.5 million unique protein/gene records. With the most comprehensive accession mapping system in DAVID 2.1, any given gene accession can be quickly mapped to another based on the user's choice. The tool also automatically suggests possible choices for the ambiguous gene accessions in the list.

   3.
The Result Page


The Right Panel:

It displays the result for the genes that has been successfully converted to desired accessions/ids of user?s choice. If a gene has multiple choices for destination accessions, they all will be displayed in independent rows.

The Left Panel:

It displays the statistics summary of gene accession conversion. For any ambiguous gene accessions, the possible conversion choices will be suggested by DAVID system and upon user?s decision for further conversion.

    4. Download/Save Results/Get Back to DAVID with Converted Gene IDs

Option 1:

highlight result content -> copy/paste to favorite text editor or excel sheet.

Option 2:

right mouse button click on ?download the list? ->select save target as-> choose destination folder -> type a favorite file name, like ?myList.txt?.

Option 3:

Click on big button on the top of right panel. It will bring back to DAVID for other analytical tools. You also find the gene IDs just converted automatically appear as a new gene list in DAVID Gene List manager.

    5. Terminology For "Conversion Summary" Table

"In DAVID DB" Column: In order to successful convert gene accession from on to the other, the user input accession has to be a valid one as user claimed in DAVID Knowledgebase. "Yes" means that DAVID mapping system covers that accession according to user claimed ID type; "No" means it is not a valid one in any types of gene IDs in entire DAVID knowledgebase, and the reasons could be: typo, completely retired accessions/ids, etc.; "Ambiguous"  means that user's accession is not good as user claimed. However, it could be other types of gene identifiers. In this case, the detail choices will be following in next table space.

"Coversion" Column:    "Successful" means the corresponding desired accessions/IDs have been found; "None" means  the desired accessions/IDs is not available; "Pending" means the mapping job not waiting for ambiguous ones unpon user's decision.
