So Dr. Pratik Jagtap is from my current stomping grounds...Minnesota. He's a research assistant professor at the University of Minnesota, Minnesota Supercomputing Institute (MSI). His work focuses on tool development for proteomic analysis specifically for Galaxy-P and he has an impressive array of publications in the field. His latest 2018 offering:Stalking his twitter account it is chock full of great links to studies and research being conducted in the are of proteomics so if that's a field of interest to you I recommend you follow his account.
In this particular presentation he was investigating the latest metaproteomic software offerings and evaluating their performance with an oral microbiome set courtesy of Rudney and colleagues 2015. He wasn't specific as to which Rudney 2015 article but I'm guessing it's this one - which appears to have links to fastq datasets from an oral microcosm study. Or it could be this publication from 2015 which Rudney is on, but not first or last author which talks about an oral microbiome dataset used specifically for Galaxy P, though I cannot be sure because the article is paywalled.
Comparison studies in bioinformatics are always informative because it sets down metrics by which we can start using to interrogate these programs and evaluate which ones are best for our experimental design, which are potentially flawed, what are the pros and cons for each such that we can justify their use or exclusion in our studies.
