Peak extender

Description

This module extends the peaks in a peak list in both directions of the retention time. The purpose is mainly to add missing data to peak lists produced by the MS/MS Peak List Builder, which only detects a single data point per peak. The extending is performed scan-by-scan in both directions by searching for data points within given m/z tolerance and above given minimal height. When no data point is found, extending is stopped.

Method parameters

Suffix
This string is added to the end of the name of each processed peak list
m/z tolerance
Maximum allowed distance in M/Z between data points in successive scans
Min height
Minimum allowed intensity for succesive scans. When intensity drops below this level, extending is stopped.
Remove original peak list
If selected, the original peak list is automatically removed
