Preparation for tutorials (if you want to follow on your own laptop, optional)
• Install matlab via your university.
• Download spm(http://www.fil.ion.ucl.ac.uk/spm/software/spm12/) andadd to Matlab path.
• Download dataset face_rep.zip fromhttp://www.fil.ion.ucl.ac.uk/spm/data/face_rep/
• Download face_rep_spm12_batch.m from the same source.
• Extract the data in a folder on your computer. Within theface_rep folder create a folder called «batches».
