is there any script missing in this box?

[Brianna-Liu]

Hi, while i was reading this toolbox guideline, i found a picture about single trial's decoding accuracy(EEG data to data.wav ),which is what i want to try in my research, but seems no such a script can caculate this and draw this picture

also, I found that even though there are 32 trials ,but the result only shows one reconstruction accuracy, i am kind of confused.

looking forward to your reply!
