Abstract: Parallel search engine in real-time or PaSER was developed together with the Yates lab to take advantage of GPU-powered database search. The GPU-powered ProLuCID-4D algorithm can process a large number of MSMS spectra generated by the PASEF process on the timsTOF platform, while utilizing all four dimensions – retention time, CCS value, m/z and fragment spectra – to increase the confidence in each identification. PaSER has now been extended into a platform that can integrate 3rd party tools enabling these tools to perform real-time analysis with generally minor adaption of their existing code. To achieve this, PaSER utilizes the concept of streams and stream processors to realize fully customizable real-time processing workflows including on-the fly decision making based on the data being generated.Summary: Parallel search engine in real-time or PaSER was developed together with the Yates lab to take advantage of GPU-powered database search.
