Occasionally there might be the need to disregard sample points when evaluating the matching criterion, for example to exclude an outlier, or to study the stability of model estimates with successive shortening of the acquisition duration.
In PKIN this can be easily achieved by (temporarily) disabling samples. First select the Measured curve by selecting it in the controls area or by CTRL+Click at a point. Then individual points can be disabled by SHIFT+Click on them. For entire ranges it is advised to zoom into the region (drag left mouse button), then activate the context menu (right mouse button) and Switch OFF all Points in visible area. This operation is illustrated below
resulting in a "shortened" acquisition for fitting purposes:
Note that disabled measurements appear in grey. They can again be enabled by a second SHIFT+Click, or by Switch ON all Points in visible area in the context menu.
