Hi Edward,

If you are using the standard specimen archive, there are limitations to what it will accept in the import compared to the Advanced Repository. The advanced repository has more functionality and would be able to take in additional columns. However, if neither option works for your needs, you can also consider using Sample Sets as a specimen repository instead (https://www.labkey.org/Documentation/wiki-page.view?name=studySamples).

With regard to grid views, if you add new fields, you will need to also enable them within the grid view as well by clicking the Grid button and selecting the option to customize the grid. The grid customizer should show the new field you added in.

Regards,

Jon
