The first time you upload an ISA-Tab file to a new project, it is the first version of that file.
While you should associate only one investigation with a project, you can upload multiple versions of an investigation file to that project, and then publish or unpublish a version as many times as you like. You may want to do this if you change your investigation data or need to fix it due to an upload error. Each time you upload a new investigation file to a project and publish it, the version number increases by one.
CSSI DCC tracks the history of each file you publish by date and time. Use the publish history timeline to switch between current and previous versions of the investigation file. You can download the full data or selected metadata of a previous version. You can only see the publish history for investigation files you have uploaded.
To view the publish history of an investigation file
- Browse or search for an investigation.
The Investigation Details page appears.
- Click History to show the timeline.
- The current version number appears above the timeline. You can hover over the version number to see the date when this version became the current version. In this example, Version 1 became current on 6/9/2017.
When a file has multiple versions, they appear on the timeline as well. The version that is currently selected is always green. In the example below, the current version is selected, so it appears in green. The current version is also open-ended to the future until you publish another version.
The white space between versions, as in the example below, indicate times when no version of the investigation file was published.
- To select a previous version, hover the mouse over the timeline. If the version you want to select is not immediately visible, move the scroll wheel on the mouse down to move left and up to move right until you see a previous version. In this example, a previous version was current only on 6/22/2017.
- Click the previous version to select it. The Investigation Details page appears, showing the selected version number at the top. You can download the full data or selected metadata of this previous version. You cannot download selected data of a previous version.
- The current version number appears above the timeline. You can hover over the version number to see the date when this version became the current version. In this example, Version 1 became current on 6/9/2017.
