Computing DAQ Score for a New Protein Model

DAQ score can be computed for a protein structure model built from a cryo-EM map on the Google Colab site or by downloading the software from the Github repository and run it locally.

    2. Major update in the search engine. Now last names of "Deposition Author(s)" of entries are included as objects of a search.
    5. 2024/06/30: Entries were updated. (209,547 unique versioned chains. Based on the data in the Protein Data Bank as of 2024/03/27.)
    6. 2024/05/31: Entries were updated. (205,353 unique versioned chains. Based on the data in the Protein Data Bank as of 2024/02/28.)

    2. URLs of minor updates of PDB entries are unified. For example, two minor versions of 7jsn_B, 22458_7jsn_B_v1 and 22458_7jsn_B_v1-0, are now redirected to 22458_7jsn_A_v1-1.
    3. Minor update in the search engine. Now a search for related entries, such as those for different chains/versions of an existing entry, are better performed from the existing entry ID as the query.
    9. 2024/02/29: Entries were updated. (194,757 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/11/29.)
    1. 2024/01/26: Added Download page.

    11. 2023/12/14: Entries were updated. (184,772 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/09/27.)
    12. 2023/10/20: Entries were updated. (182,286 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/08/30.)
    13. 2023/10/19: Entries were updated. (177,876 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/07/26.)
    1. 2023/09/11: Entries were updated. (172,916 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/06/28.)
    2. 2023/09/11: For about 7% of entries, DAQ scores were somewhat revised. revised Entry ID list
    15. 2023/07/03: Entries were updated. (167,288 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/05/31.)
    16. 2023/05/31: Entries were updated. (162,355 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/04/26.)
    17. 2023/04/27: Entries were updated. (158,838 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/03/29.)
    18. 2023/03/13: Entries were updated. (152,129 unique versioned chains. Based on the data in the Protein Data Bank as of 2023/02/08.)
