Error using Fullfile

[KimHu123]

Hi there!

I'm using the swa_SW_Template since I would like to look into the SW characteristics. I have already preprocessed the data and created an .set file. Whenever I run the swa_SW_Template it throws the error:

Error using fullfile Char inputs with multiple rows are not supported. Caused by: error using horzcat Dimensions of matrices being concatenated are not consistent.

I'm not sure how to solve this and I was wondering if you could help me :)
