Analysis software for VU-AMS Core: CoreLab

Download CoreLab (formerly VU-DAMS core)

Click the name of your operating system to download the latest version of CoreLab 7.0.x for

Windows

Note: If the Windows installer is blocked by Microsoft Defender SmartScreen you can still install it by right clicking the .exe file –> Properties –> check the Unblock box –> click on Apply. Then install by double-clicking again.

This is a temporal fix until the program has its reputation regained with Microsoft after the name change. The signing certificate is still correct.

macOS ARM architecture (approx. built 2021 and later)

macOS Intel architecture (approx. built before 2021)

Executable jar for Linux

Sample data

A sample 2 hour data file of an individual traveling to a football stadium and watching the first half of a football match (Ajax – Vojvodina, 1-0) can be found here (unzip before opening in CoreLab): sample_data_watching_football

Troubleshooting Windows

• Your virus scanner may detect a false positive for the programme and quarantine the executable. Check if you have new alerts from your Windows defender/virus scanner related to “PUA:Win32/Puwaders”. Click on the notification and “allow”. Then reinstall the VU-DAMS beta software

Troublehooting MacOS

If VU-DAMS does not start on MacOS, first try to start it on command line:
– open the Terminal.app
– go to your Applications directory by typing: cd /Applications
– run: open VU-DAMS.app
If this resolves your problem, unfortunately you will have to keep starting it like this for now. We are working on a fix for the double click start.

Otherwise the most like cause is the Java installer has not set the required environment variable JAVA_HOME.
To fix this:
First get the required value to put into this variable:
– open the Terminal.app
– run: /usr/libexec/java_home
– copy the output (eg. /Library/Java/JavaVirtualMachines/jdk-21.jdk/Contents/Home)
– open the settings file ~/.zshrc in a text editor; for example: nano .zshrc
– add the following to the bottom of the file: export JAVA_HOME=”<the path you just copied>”
– restart the Terminal and try to start VU-DAMS again
