Feature filter¶
Description¶
Feature list methods → Feature list filtering → Feature filter
This module deletes features in a selected feature list that do not meet the requirements defined by the user. The filter is performed separately on each raw data file in the peak list.
Parameters¶
Name suffix¶
Suffix to be added to feature list name.
Duration¶
Peaks with a duration outside the entered range will be removed.
Area¶
Peaks with an area outside the entered range will be removed.
Height¶
Peaks with a height outside the entered range will be removed.
# data points¶
Peaks with fewer data points than the entered range will be removed.
FWHM¶
Peaks with a FWHM outside the entered range will be removed.
Tailing factor¶
Peaks with a tailing factor outside the entered range will be removed.
Asymmetry factor¶
Peaks with an asymmetry factor outside the entered range will be removed.
Minimum RT shape score¶
(since mzmine 4.7)
Tries to fit a chromatographic peak with a Gaussian, a bi-Gaussian, or two Gaussian functions. The Gaussian function models an ideal case. The bi-Gaussian models each side with by a different gaussian function, creating a fronting or tailing gaussian. The model with two Gaussian functions describes a feature that has not been completely resolved during the feature resolving step. Features with less than 5 points will be removed automatically.
Minimum mobilogram shape score¶
(since mzmine 4.7)
Tries to fit a mobilogram with a Gaussian, a bi-Gaussian, or two Gaussian functions. The Gaussian function models an ideal case. The bi-Gaussian models each side with by a different gaussian function, creating a fronting or tailing gaussian. The model with two Gaussian functions describes a feature that has not been completely resolved during the feature resolving step. Features with less than 5 points will be removed automatically.
Top to edge ratio¶
(since mzmine 4.7)
Determines the top-to-edge ratio of the chromatographic peak by dividing the highest by the lowest point of the feature ( see feature resolving).
Keep only features with MS/MS scans¶
Peaks without any MS/MS scans will be removed.
Remove source feature list after filtering¶
If the checkbox is selected, the source feature list will be removed, and the filtered version will remain.
