[FieldTrip] problem in importing my data in fieldtrip

[Moumita bhowmick]

Hello everyone,
Just to inform you that my problem has been resolved. The code that I tried
this time was:

cfg = [];
cfg.dataset = 'F:\data_fldtrp\1_MD_1_edtd.mff';
cfg.trialdef.eventtype = '?';
ft_definetrial(cfg);

I think fieldtrip doesn't recognize the .set file. It worked well with
.mff.
