Zapping

Zapping replaces a user defined number of data points in a 2D data object or 3D data objects by values of a linear function. The user can adjust the starting and ending point of data replacement either graphically or by entering discrete data point values.

Zapping is performed as follows:

Apply zapping operation to multiple data objects at the same time. If you merge multiple spectra in one data view, zapping will be applied to all objects in the current view.
