My data is already preprocessed and averaged over trials. It is saved in .mat files as 2 seperate 3D arrays for 2 conditions where CONDITION1(potential,channel,subject), then a seperate 1D array for time points of potentials TIME(1,timepoints) and .m file with channels' coordinates. I could not find the answer in help how to import this kind of data format. Please help.
