Peakjuggler is a Proteome Discoverer node for label-free quantification of peptides and proteins.
We have a forum. Feel free to ask questions and give feedback!
We benchmarked Peakjuggler on a publicly available dataset (Ramus et al). The original raw files are available on PRIDE (PXD001819). The samples are comprised of UPS1 protein mix spiked in at different concentrations into a 1:1 yeast background. This dataset was used in a comparison for different LFQ algorithms (Veit et al). We used results published there as Supplementary Data in order to compare the performance of Peakjuggler to LFQProfiler(OpenMS), MaxQuant, MFPaQ and Skyline.
Peakjuggler outperforms these tools by enabling the detection of more differentially abundant UPS proteins at the same number of falsely identified (unregulated) yeast proteins.
The Proteome Discoverer workflow to reproduce this result is available for download and provides a starting point for easy incorporation of Peakjuggler in your workflow. Furthermore the final results file is also available here.
