Search residual spectrum

This command is used to perform an additional search with the residual spectrum of a previous search. The residual spectrum is created by subtracting the search spectrum and the result spectrum of a search. Please refer to the tutorial How to search spectra for details on the search function.

The Search Residual Command is only available if there is an active result of a previous search.
