DATASET ROW SELECTOR FOR CALIBRATION¶
Selects a single representative row from a dataset for use in material calibration workflows. Given a target column (curve or numeric), it applies a multi-criteria pareto-front selection — using either raw values or distance-from-median — to identify the row that best matches the specified criteria (e.g. min slope, min integral). Use this worker to automatically pick the most appropriate test curve or data point before fitting material parameters.
When to use¶

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset With Test Data | dataset_1 | dataset | — | ✓ | Input dataset containing test data rows; each row typically represents one test coupon or simulation result, with at least one curve or numeric column used for selection. |
| Column To Use For Selection | col | text | — | ✓ | Name of the column to use for row selection; if the column contains curves, the curve closest to the selection criteria is returned — if numeric, the row whose value is closest to the standard deviation threshold is returned. |
| Selection Criteria | criteria | dataset | (complex) | Table of curve feature criteria used for pareto-front ranking; each row specifies a feature name (e.g. slope, xmax, ymax, xatymax, integral), the comparison direction (min/max), and whether to include it — defaults to all features set to ‘min’ if not provided. | |
| Type Of Data To Use | data_type | scalar | median | Controls whether the pareto-front is computed on raw column values (‘raw’) or on each row’s distance from the median (‘median’, default); use ‘median’ to find the most representative/central specimen. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_get_curve_for_calibration_output_1 | curves_get_curve_for_calibration_output_1 | dataset | Single-row dataset (or associated curve) corresponding to the selected representative specimen; ready to be passed directly into a material parameter calibration or curve-fitting worker. |
