Title
|
PowerGet analysis for detection of all peaks (C2)
|
Description
|
Raw data files are converted to text file by MSGet software without cut off value and peaks are extracted from the text files by PowerFT with parameters (intensity cut off=5000, peak selection filter is default, peak shape is manually checked for peaks with intensity < 1000).
