ft_timelockbaselline gives an error when the data has data.dimord = 'subj_chan_time'. The function always searches first for data.avg struct. But data.avg is not present when data.dimord = 'subj_chan_time'. For now, I fixed this by commenting line 100-108. Best, Mark Noordenbos

Changed the status of bugs without a specific owner to UNCONFIRMED. I'll try to replicate these bugs (potentially involving the submitter), and change confirmed bugs to NEW. Boris

Dear Mark, Could you provide a simple script to reproduce this problem, and describe your actual output, and what you think is the correct output? Best, Boris

(In reply to comment #2) Dear Boris, Data = label: {30x1 cell} time: [1x400 double] individual: [19x30x400 double] dimord: 'subj_chan_time' cfg: [1x1 struct] cfg=[]; cfg.baseline=[-0.1 0]; Data=ft_timelockbaseline(cfg, Data) the input is timelock data with 30 channels and 400 timebins ??? Reference to non-existent field 'avg'. Error in ==> ft_timelockbaseline at 107 timelock.avg = ft_preproc_baselinecorrect(timelock.avg, tbeg, tend); Best, Mark
