Adding and running nodes
Explains how to add new nodes into a project and use them to load an image file. Afterwards, the project is saved.
Tutorial: Adding and running nodes
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).
Now the new
File node will appear on the work area.
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
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).
To choose a concrete file, click on the navigation tab (red arrow 1), navigate to the folder where the image file is (red arrow 2), and choose the image to be loaded (red arrow 3).
Run the node by clicking on the green arrowhead inside the node (red arrow), …
… and then selecting one of the top two options
Update cache or
Cache intermediate results.
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.
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)
File node packages the file path into a JIPipe-managed object called
File. If you double-click a
Path, it will be opened using your system’s standard behavior.
To save the project, go to the
Project tab (red arrow 1) and select the saving mode, e.g.
Save As (red arrow 2)
The navigate to the target folder (red arrow 1) and select or choose a file name (red arrow 2). The JIPipe project filenames end with the “.jip” extension.
