Modifying P300 Speller Matrix

Post by A_Foxglove »

Hello,
I am a third year student at the University of Sheffield. I am currently working on my Final Year Project, which involves comparing the accuracy in using a P300 Speller in patients with ADHD and neurotypical patients. Part of this requires modifying the matrix used in the speller to a 3x3, 4x4, and 5x6 sizes.

I have attempted to do so using both Glade, and also by modifying the UI files manually in notepad. Both methods have produced the same error, which is "Could not load interface file" and "The file may be missing. However, the interface files now use gtk-builder instead of glade. Did you update your files?". As far as I can tell, there is nothing different between a .ui file that does work and one that doesn't, but I have clearly missed something.

Is there another methodology to modify the matrix sizes that I have missed? Is there another piece of software I need to modify the matrix sizes? I would like some assistance with this if at all possible.
