Getting PRIDE Inspector

Installation Requirements

  • Java: Java JRE 1.7 (or above), which you can download for free here. (Note: most computers should have Java installed already).
  • Operating System: The current version has been tested on Windows 7, Windows Vista, Linux and Max OS X, it should also work on other platforms. If you come across any problems on your platform, please contact the PRIDE Help Desk.
  • Memory: MS dataset can be very large sometimes, in order to get good performance from PRIDE Inspector, we recommend you to have 1G of free memory.

Launch via Webstart

Click here to launch directly the latest PRIDE Inspector.

Please note that Mac OS 10.8 (Mountain Lion) users or users of the Google Chrome browser, may have to execute additional steps. Please see FAQ section below if in doubt.


You can get the latest PRIDE Inspector from our Download Section, and download (where X and Y represent the version of the software). Unzipping the file, creates the following directory structure:

pride-inspector-X.Y pride-inspector-X.Y.jar log lib examples config

To start the software, simply double-click the file named pride-inspector-X.Y.jar. If this fails, try to download and install Java 1.7 or above, as explained in the previous section. (The program can also be started from the command line using the following command: java -jar pride-inspector-X.Y.jar.)

The zip file contains also an examples folder with 2 sample files: one in mzML format (mzml-example.mzML) and the other in PRIDE xml format (pride-example.xml) so you can upload them in pride inspector and try the application. There is and additional folder, config, that contains a file called config.props where you can modify the amount of memory assigned to your application (only change if you are trying to view files and is causing the software crash because of a "Out of memory..." exception). The additional 2 directories, lib and log, contain all the java libraries necessary for the application to run and some debugging information if the application crashes.

##Maven Dependency

PRIDE Inspector can be used in Maven projects, you can include the following snippets in your Maven pom file.

<!-- EBI repo -->

<!-- EBI SNAPSHOT repo -->

Note: you need to change the version number to the latest version.

For developers, the latest source code is available from our SVN repository.


Mac OS X App Gatekeeper Message

If a user downloads the PRIDE Inspector software onto Mac OS X 10.8, they will see a scary warning:

"PRIDE Inspecor can’t be opened because it is from an unidentified developer"

Mac Error


1- Solution 1: To override your security settings and open the app anyway:

- In the Finder, locate the app you want to open. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
