To be honest, I don't know what the TPP project is intended for. As far as I understand, this is a set of tools to assist in research of proteins and their interaction in living organisms. However, that's not so much important. What is important is that their source codes are open. It means that I can check them with the PVS-Studio static analyzer. Which I'm very much fond of.
So, we have checked the Trans-Proteomic Pipeline (TPP) version 4.5.2 project. To learn more about the project, see the following links:

• Source code;
• Wikipedia: TPP;
• Seattle Proteome Center: TPP Wiki.
