Again, if you only have one trial you should put your time vector in this one cell. > The answer to the previous apply to the .label I suppose. Actually, no. .label is a different kind of creature - it is a cell array of strings with your channel labels so it is a (nchannels x 1) array no matter how many trials you have. Perhaps you should look at the example script \toolbox\Neural_Models\spm_lfp_txt2mat and modify it to suit your needs. Best, Vladimir
