There is a function which allows you to upload or download metadata, but why would be it important?
Let see the main reasons:
- You want to do something with the metadata on your own computer
- You want to upload some new metadata connected to one of your session
- You want to change some metadata connected to one of your session
So, you can export and import metadata, with the following steps.
- After you logged in and chose the corresponding project, you have to go to 'My Data' and click on 'Other options'. Here you should select 'Export Metadata'. Here you can select to be contained your would-be file the title, type and ID row. These are the most basic ones, which could be partitioned by Gender, Handedness, Age at scan or Gray Matter volume or whatever the chosen data contains.
- After you chose what you want to see in your CSV file, you just have to click on 'Prepare CSV file' button. (In this case, your CSV file will contain 4 rows which partitioned by 2 columns the Gender and the Handedness. The fourth row the data itself.)
It is really important to know in which subject which session ID do you want to upload or exchange! If you want to create a new metadata subject or in an existing subject you want to create a new Session than please use the following form: 'subjectname/sessionID'
Also be aware, that if you import metadata you will overwrite the old ones. Old ones are accessible from the history but the system will use the new imported metadata.
- If you want to import some CSV file, what you have on your computer, please do as before until the clicking on 'Other options'. Now please, select 'Import Metadata'.
- After you successfully uploaded the new metadata CSV file with a good format you will be able to see the changes on the summarizing table under 'My Data' or you will see the new metadata line with the new Session ID or also with the new Subject ID as well.
Note: It doesn't matter whether you select an existing Session or not, because the uploading is driven by the above-mentioned Subject and Session ID.
Here, there is the other option called 'Show only the parameters from the CSV file'. This option could be useful if you want to recompose the appearance of the table about your metadata. It doesn't mean that you will delete i.e. old columns from the dataset, it just will modify the appearance whit which you can much more easily see what kind of datasets you have.
Where can you check what was the old value of a metadata?
When you overwrite a data with import, you can still check from which value you changed the dataset. To do so, follow the following steps:
- Select the considered session which had been changed
- Click on 'Other options', select 'Edit session'
- If you click on the double square arrow icon, the popup will tell you what kind of changes were made by whom and when.
