The number of mass peaks displayed in a deconvoluted spectrum can be controlled in two ways:
Using the 'Compute' Dialog
Click 'Compute' and set the 'Max number of mass peaks' in the 'Intact options' dialog that appears. This setting defines how many entries are shown in the Masses table and how many peaks are annotated in the deconvoluted spectrum. In the example below, the 10 most abundant Masses are annotated.Using an Advanced Command
You can also control the number of displayed peaks by Mass relative intensity with the following advanced command:
[Intact]
MinBasePeakRatio = 0.05
In this example, only peaks with a relative intensity of at least 5% compared to the base peak (the peak with the highest intensity) are considered. MinPeakMass and MaxPeakMass lines can also be added to limit Mass peak assignment by Mass Range.
[Intact]
MinBasePeakRatio = 0.05
MinPeakMass = 145000
MaxPeakMass = 160000
In this example only peaks with a relative intensity of at least 5% compared to the base peak and within the Mass range of 145,000-160,000 Da are considered.
This advanced command can be set either during project creation or after a project has been created. The figure below shows how to include the advanced command in the workflow and apply on project creation.
The figure below shows how to adjust/add and apply the advanced command post-project creation.
