The intervals between two\r\nsessions varied from several days to several months.\r\n\r\nA trial started by a short beep indicating 1 s preparation time,\r\nand followed by a red arrow pointing randomly to three directions (left,\r\nright, or bottom) lasting for 5 s and then presented a black screen for\r\n4 s. The subject was instructed to immediately perform the imagination\r\ntasks of the left hand, right hand or foot movement respectively according\r\nto the cue direction, and try to relax during the black screen.\r\n\r\nReferences\r\n----------\r\n\r\n[1] Zhou B, Wu X, Lv Z, Zhang L, Guo X (2016) A Fully Automated\r\n       Trial Selection Method for Optimization of Motor Imagery Based\r\n       Brain-Computer Interface.
