Step 1

From the main GUI. Type a keyword into the search bar (red arrow 1), e.g., looking for way to add a file to the pipeline at the beginning. Then choose the desired node, in this case we go for adding a file (red arrow 2).

Step 2

Now the new File node will appear on the work area.

The File nodes contains information where JIPipe should look for files. It is related to Folder (a directory) and Path (a file or directory).

If you want to reference multiple files/directories/paths, you can also use File list/Folder list/Path list.

When the new node is clicked on and activated, it will be surrounded by a dashed rectangle(red arrow 1). Make sure that the Parameters tab is active on the right side(red arrow 2).

Step 7

The result will be shown on the right side, under the Cache browser tab (red arrow 1), where the newly loaded file name and full path will be listed (red arrow 2)

The cache stores the results of a pipeline/node in memory. Please note that to work with large images, you require a computer with sufficient RAM space.

Step 8

By double-clicking on the cache entry row (red arrow 1), the newly loaded image will be opened in a dedicated viewer (red arrow 2)

The File node packages the file path into a JIPipe-managed object called File. If you double-click a File/Folder/Path, it will be opened using your system’s standard behavior.
