Fill a scalar aux target#

The shipped builder no longer asks users to draw aux wires on a DAG canvas. Operation-valued parameters are side-loader targets. Selecting a target marks it green; clicking a compatible palette operation fills it.

This walkthrough uses FilamentousFungiDetector.inoculum_detector.

Step 1 - Add the consumer#

Open the Builder tab, then click GaussianBlur, ContrastStretching, and FilamentousFungiDetector in the palette. The main chain is fixed and left-to-right:

Main linear chain with FilamentousFungiDetector selected.

The side loader shows inoculum_detector as a required side value. Until that value is filled, the issue badge remains active.

Step 2 - Select the side port#

Click the gold port button beside inoculum_detector in the side loader. The port turns green and the active target strip names the parameter you are about to fill:

inoculum_detector side port selected as the green active target.

This is the same target-selection model used by the floating continuation port on the map. The next compatible palette click goes to the green target.

Step 3 - Choose the aux operation#

Click OtsuDetector in the palette:

inoculum_detector filled with an OtsuDetector side value.

The builder creates a hidden aux source, records it in the DAG state, and keeps the visible map linear. The filled row can be replaced, cleared, or inspected from the side loader.

Reference#

  • No drag gesture - aux fill is click-only in the default builder.

  • Compatibility - incompatible palette choices leave the pipeline unchanged and show a warning.

  • Doc help - click ? beside the parameter or filled value to read the docstring.

  • Preview - image-output and continuation port menus can preview a prefix; global preview/save still require the whole pipeline to validate.
