Hi Ben, 

Thanks for the reply. This was a great help. I managed to make some progress using a Windows machine and an older version of MATLAB (2010a), but got as far as loading the FEAT directory, but then got this error:

14-Jan-2016 14:51:16 | ERROR | wfu_results_viewer.m | MException thrown. Stack follows:

Do you have any idea where this error is coming from?

There is no SPM.mat file in my FEAT directory.  

There is a progress bar ("Create xSPM structure") that is also on screen when this error comes up, but the bar only reaches halfway.

Thanks, 

Elliot.
