In the procedure part of the event-related averaging tutorial the megplanar function immediately follows the combine planar function, however, in the script of the same tutorial, the timelockanalysis function is running between the two functions: cfg = []; cfg.planarmethod = 'sincos'; avgFICplanar = ft_megplanar(cfg, avgFIC); cfg = []; avgFICplanar = ft_timelockanalysis(cfg, avgFICplanar); avgFICplanarComb = ft_combineplanar(cfg,avgFICplanar); I guess the script is right and not the procedure (or the figure of the procedure).

OR: is the order of the two functions interchangeable?

this was for an older FT version. The single trial avg is converted to a single raw trial and then processed. Previously this resulted in a single raw trial output, which was then converted back into timelock by the call to ft_timelockanalysis. Now it is already converted back to timeklock inside the megplanar function.

I removed the extra timelockanalysis line bw megplanar and combineplanar in the script of the tutorial Lilla
