Title	PowerGet analysis for annotation of peaks with MS/MS
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). The replicates data are aligned by PowerMatch with blank data. The alignment is manually edited. Assigned peaks observed in multiple replicate samples are selected for annotation process.
