This new version of ADIT (2.0) indicates file format errors with suggestions for solutions; automatically validates the structure; checks for consistency between sequence and coordinates; allows easier organization of sequence information; and simplifies entering author, title and citation information. It is designed to improve data quality and processsing efficiency.

Beginning June 14, this new version of ADIT will become the default site for deposition on selected days each week for testing. The date of full deployment of this tool will depend upon the results of this testing.
