Title
|
PowerGet analysis for detection of all peaks (C1)
|
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=10000, peak selection filter is default, peak shape is manually checked).
|
Comment_of_details
|
At first, all peak shapes were manually selected by eye at both peak selection step and peak assignment step to make a reference data set. The data set was manually annotated after database search process. Then data sets made by different values (cut off intesity=0, 1000, 5000, 10000, 50000, 100000 in peak detection step) without manual check at peak selection step were manually annotated after database search process. The selected value (5000) showed >90% coverage of metabolite annotation of the reference data set.
