This is Shingo. Thank you for the quick and kind response. I have managed to get the matrix by STUDY variable in the Matlab workspace. Thank you very much again. However, another question has arose. As you said, I have got "erspfreq as vertical axis.” When I specify frequency band as 3 to 30, the number of rows is 81. I wonder “81” is (30-3)*7. Is this the correct understanding? If so, where in my preprocessing or plotting is the number of rows determined. Thank you in advance again.<br>
<br>
Sincerely,<br>
<br>
