Jörn M. Horschig - 2013-03-28 10:13:54 +0100 Required fields: - label, dimord, time that doesn't seem right, .avg is not required? with label, dimord and time, it could also be freq data. also, on top it says: FT_DATATYPE_FREQ describes the FieldTrip MATLAB structure for timelock data

Hm. At the moment (of the current code that is), it does seem that .avg should be required. However, if I ever get around to finalizing bug 656 of making it possible that ft_timelockanalysis can compute only a .cov and not an .avg, then .avg should not be required, but rather either a .avg or a .cov required. Certainly the typo in the comments should be changed for the _FREQ thing!

it can also contain timelock.trial as 3-D array, which has dimord=rpt_chan_time. However, I would indeed expect either avg or trial (not as cell-array as in raw data, but as 3-D array) to be present.

Updated the _FREQ bit, and also allowed 'avg' as an optional (not required) field, in the comments section. Updated via pull-request on Github
