Summary of single-trial decoding accuracies (%) across all 9 subjects for overt and imagined movements

	S1	S2	S3	S4	S5	S6	S7	S8	S9
Overt	88.6	69.0	72.4	77.8	57.9	57.0	51.3	82.2	56.6
Imagined	95.0	69.9	71.9	45.8	62.5	39.6	73.7	44.3	45.2

Subjects S1–S5 performed the nondelayed center-out task, and subjects S6–S9 performed the delayed center-out task. MEG sensors above the sensorimotor area were used. The time window for decoding analysis was determined based on the sensor-space MANOVA analysis. MEG signals within that time window were averaged. Intended movement direction was decoded using a Bayesian classifier with leave-one-out cross validation. The chance level is 25%. The average decoding accuracies across all subjects are 67 and 62.5% for overt and imagined movement, respectively. MEG, magnetoencephalography; MANOVA, multivariate ANOVA.
