J-AST Help

E-Test strip presets

E-Test strips come in different designs, each with a specific sequence of concentration markings (ticks). J-AST uses strip presets to map the detected tick positions to actual concentration values. This information is essential for the MIC detection algorithm.

Built-in presets

J-AST ships with the following built-in strip presets:

  • E 256-0.016

  • E 32-0.002

Managing presets

To manage strip presets, click the Presets button in the top toolbar (visible when logged in as a regular user or administrator). This opens the presets manager page.

From here you can:

  • Add a new strip preset by providing a name and defining the tick sequence

  • Edit an existing custom preset

  • Delete a custom preset

Annotating images with a strip preset

Each E-Test image can be associated with a strip preset. To do this:

  1. Select an E-Test image in the project view.

  2. In the right-hand properties panel (Edit tab), locate the Strip preset annotation button.

  3. Click the button to open the strip preset selector dialog.

  4. Choose the matching preset from the list and confirm.

Matching strip presets automatically

If you have E-Test images with unknown strip presets, J-AST can match them to the preset library by comparing the detected tick sequences.

  1. Select the E-Test images you want to match.

  2. In the right-hand properties panel, switch to the Process tab.

  3. Search for Match strip presets to library and click it.

  4. Confirm to start the matching process.
