How to set the baseline in TFRs results plot?

[Robert Oostenveld]

Hi 李卫娜,

The baseline depends on the interval that is available prior to  
stimulation in which you can estimate the time-frequency resolved MEG  
power. If your subject is intermittently tapping, then you should  
choose the time between the tapping. If the subject is continuously  
fingertapping, then you should do the baseline correction differently  
by estimating the power in a section of your experiment in which the  
subject was resting.


best regards,
Robert
