Hi, I'm new to this community. Glad to be part of it. I recently started working on Clustering of proteins and I read few papers related to that. In few of the papers the datasets used were Gavin, Collins and Krogan. I want to do few experimentation but I looked all over the internet and I couldn't find the dataset . I also tried contacting author but no luck. Here is the paper http://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0091856&type=printable .
