Hi, 
I downloaded NiiStat and the demo data to test.
However whener I run as mentioned on the tutorial page, I get the below error.
Could you please advise on how to solve this issue?
I have a Matlab 2016b version and using an iMac with a macOS Big Sur version 11.4.

Thank you for your help

Hello Salem,

The latest version of NiiStat (which can be run using the NiiStatGUI command) requires a later version of Matlab than you have installed, so you should upgrade to the latest version if possible.

Alternatively, you can still run the legacy version of NiiStat (which does not have a fancy GUI).

That can be downloaded here:
