The other alternative is to run XPRESS in Label-free mode. For peaks where it can extract intensities, it will report two results: one for the integrated area with corresponding scan range, and one for the maximum peak intensity along with the scan number of that peak. You can view and export these values in the PepXMLViewer. Unfortunately, they cannot be used for quantitation of proteins within TPP tools.
If you are looking to quantify proteins, we do recommend that you give StPeter a try. Its main algorithm is based of fragment ion intensities from corresponding PSMs, although it can also report a value based on spectral counting. Hope this helps. --Luis On Fri, Oct 2, 2020 at 12:06 AM vipulb...@gmail.com <vipulbatra...@gmail.com> wrote: > I am a using TPP v5.2.0 Flammagenitus to analyze label free data > generated on a Thermo QExactive machine.
