If your user account has the Write or Own permission level on an existing collection in DME, and if that existing collection has been configured to contain data files, you can upload a data file to that collection. This page describes how to register one data file at a time. For instructions on registering multiple files, refer to Uploading Data in Bulk via the GUI - 20190926.
To register a data file:
- Log in as described in Logging In via the GUI. The Dashboard appears.
- Select a method:
- If you are not familiar with the data destination, browse for it, as described in Browsing for Data via the GUI. Navigate to and right-click the location where you want to register your data file. Click Add Datafile. The Register Data File page appears.
- If you are familiar with the data destination, select this method: In the left panel, click Register > Data File. The Register Data File page appears.
If you browsed to the data destination, that portion of the page has only the Data File Path field, with a system-generated collection path already specified.
If the Base Path and Collection Type fields are available, specify the data destination:
- Select the base path specified by your group administrator. The system begins to populate values in the Collection Type field and the Data File Path field. (If you are a group administrator and want the Collection Type field to list more collection types, contact NCIDataVault@mail.nih.gov.)
- Unable to render {include} The included page could not be found.
- Select the base path specified by your group administrator. The system begins to populate values in the Collection Type field and the Data File Path field. (If you are a group administrator and want the Collection Type field to list more collection types, contact NCIDataVault@mail.nih.gov.)
- Specify the data source:
Consider specifying a checksum for validation of data transfer. By default, the system does not perform this calculation because it can increase the time required to register the data, depending on the file size.
