<p class="MsoNormal">I think if you use cfg.inputfile, this field needs to contain the path to a .mat file, not a variable in the matlab working space. If you want to load the data into the matlab working space and then run timelock analysis on this data, you
can create a cfg structure without a field named ‘inputfile’. Instead, you put the variable containing the data as the second input variable of ft_timelockanalysis.<o:p></o:p></p>
