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 from the most popular resources including NCBI, Ensembl and UniProt. With the comprehensive identifier mapping system in DAVID, many given gene/protein identifiers can be quickly mapped to another based on the user's choice. The tool also automatically suggests possible choices for the ambiguous gene/protein identifiers in the list.

3. The Result Page

The Left Panel:
Displays the statistics summary of the identifier conversion. For any ambiguous identifiers, the possible conversion choices will be suggested by the DAVID system so that the user may decide how to proceed with the conversion.
The Right Panel:
Displays the result for the identifiers that have been successfully converted to the desired identifier type. If the original identifier has multiple conversions for the chosen conversion type, they will be displayed in independent rows.

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 the "Submit Converted List to DAVID" button on the top right. This will load the converted list into DAVID as a new list for being used with other analytical tools.

5. Terminology for "Conversion Summary" Table
|
|
In DAVID DB" column:
In order to successfully convert identifiers from one type to another, the user's input identifiers must be found in the DAVID Knowledgebase. "Yes" means that the identifiers were found in the DAVID Knowledgebase based on the user specified ID type; "No" means it is not found in the DAVID Knowledgebase with possible reasons such as a typo in the original identifier, it is a retired accession/ID, etc.; "Ambiguous" means that the user's identifier can be mapped to multiple id types. In this case, the possible choices will be outlined in the table below the summary to the inform the user's choice of which type is correct.
"Conversion" Column:
"Successful" means the corresponding desired accessions/IDs have been found; "None" means the desired accessions/IDs are not available; "Pending" means that the identifier is ambiguous and requires the user to choose which is the correct type.
