Can you not use the techniques you learned from your previous question http://www.mathworks.co.uk/matlabcentral/answers/104691-i-need-to-plot-the-eeg-in-matlab-i-have-downloaded-the-data-base-which-is-in-txt-format-bt-i-am ? You would change the file name in the load(), but then you would need to know the variable name.
