The Feature Mapper node maps quantification consensus features onto proteoforms within the tolerances specified by the node.

The following table lists the node parameters.

Table ProSightPD Feature Mapper node parameters

Parameter

Description

1. Consensus Feature

Feature Presence in File Threshold

Species minimum percentage of files a species must be quantified to return a quantitation result.

For example, if the threshold is set to 30%, then a proteoform must be detected in at least 30% of the files analyzed to report a quantitation value.

2. Consensus Features Group/Proteoform Connection

Feature Group Proteoform Connection Time Tolerance (Minutes)

The maximum allowable separation in time for two feature groups to be grouped together.

Feature Group Proteoform Connection Mass Tolerance (Da or ppm)

The maximum allowable mass difference for two feature groups to be grouped together.
