Trans-Proteomic Pipeline (TPP) software, release 6.2.0 is a major release of TPP that contains new features, improvements, and fixes to 6.1.0. The software is available for Windows as well as Linux (and unofficially) for OSX from all the usual locations (please see the section below, "Getting the software"). Most users are recommended to use the Windows installer, which installs and configures the TPP and other required software (such as a web server). For advanced users who need to customize the TPP, or for those who run on Linux or OS X, you can download the source code. Again, most users don't need build from source, and should use the Windows installer.

For installation help, please see TPP:5.2_Installation (same as for 6.1.0)

  • HardKlor

  • NeoPepXMLParser
    • Added new element <lability> to <ptmprophet_result>. I have no idea what this is because it is not in the PepXML schema.
