Data Upload

The data upload process allows users (once you have registered and logged in) to copy one or more experimental data files from their local computer to the storage repository on the CARMEN system. In the process, users can organise their data using folders, attach extensive metadata documents, and set sharing permissions.  On this page we will show how to upload with minimal metadata, and with access permission set to private.

Assuming you are logged into CARMEN and in the workspace view, click on the UPLOAD button

You will then see the metadata panel, which will take up the whole of the browser window. The default metadata document is based around electrophysiology. It is rather an extensive document, so in order to aid users, especially for repetitive data uploads of similar data, we allow users to create templates. For more information on metadata documents and templates click here. We encourage users to make full use of the metadata document, as it adds so much value to your data files, both for yourself going into the future, and to others. However, for the sake of this example, we will only enter the minimum metadata required. This is the name of the experiment that the data is sourced from – in this instance, the name is “My example upload”.

Once the metadata is complete, clicking “Next” take you to a panel that allows you to select a location for the data in your online data space.

Note that you can create, delete and rename folders from this panel. Once you are happy with the target location for the new data, click “Next“.

The next panel opens a file browser view into the local file system on your computer. This allows the user to select the files that you want to upload onto CARMEN. The browser is part of a Java applet so there may need to be some interaction with Java to start the applet. With the file browser you can select one or more files from within a folder, or you can select a folder to upload including any files and subfolders within it. Clicking “open” on the file browser will show you which files you have selected for upload (see below).

  • Remove – will remove selected files from the table;
  • Clear – will remove all files from the table;
  • Browse – reopens the file browser so that you can select additional files;
  • Upload – Once you are happy with the file selection, clicking upload will send your data to the CARMEN server;

So to continue the process, click upload – you will see a status message appear underneath the upload button. Upon completion, the status will read “Upload Complete”.

You can now click “Next” to view the sharing panel. This panel allows you to set sharing permissions on both the data itself and the associated metadata. The options for sharing on both the data and metadata are:

  • private – visible only to the owner of the data/metadata;
  • shared – you can specify specific users or groups;
  • public – everyone logged onto CARMEN can see the data/metadata;

Generally, you would give the same sharing rights to both data and metadata, in which case there is a tick box at the top of the panel so that you only need to set the permissions once.  However, you may with to make the metadata visible to others, without sharing the data, and this is possible with this panel.

Clicking “Next” completes the upload process.

The data should now reside in your data space at the desired folder location.
