Beginning of Tree Branching

Specifies the minimum number of tree sections the algorithm creates from the initial spectral tree. The value determines the MS stage where a division of a spectral tree takes place.

Specifies the minimum percentage that two spectral trees within adjacent tree sections must match before the algorithm considers the two spectral trees as the same component. Matching spectral trees is defined as having identical precursors up to the level specified by the Minimal Tree Depth value and a Tree Match Factor value that exceeds the specified value.


Wide Component Merge Mode

Enables a comparison of the spectral trees for potential matching and merging, not only in adjacent sections, but also in sections up to the distance specified by the Allowed Gap value.

When comparing the spectral trees for potential merging, specifies the maximum distance between nonadjacent tree sections.


Analyze only Current Filter


Specifies only a part of a chromatogram to be analyzed (time range), which can speed up your work. In this case, the algorithm ignores regions outside of the specified range.


m/z Range

Determines the m/z value range that is analyzed. Ignores other spectral regions. This feature is useful when processing large chromatograms.

Resets the chromatogram to its original (before component detection) state.
