If your user account has the Read , Write, or Own permission level on a collection, you can download a data file in that collection to your file system. The dm_download_dataobject_presigned command gets a pre-signed URL from DME and uses it to download data directly from the NCI Data Vault, instead of through DME.local system.
Run the following command:
...
| Parameter | Description |
|---|---|
| [-h] | If you want to print a usage (help) message for this command, specify this option. |
| [-D <REST-response>] | An optional parameter, specifying a path and filename in your file local system. The system always creates a response file:
|
<source-path> | A path within DME. Specify the data file that you want to download. |
<destination-file> | A path in your file local system. Specify where you want the system to create the downloaded file. The destination folder structure you specify must already exist. |
The following example downloads a sample.txt file from the Project_Orig collection in DME to a JaneDoe folder in Windows.
