[FieldTrip] RE : problem in importing my data in fieldtrip

[Eva Masson]

Hi Moumita,

Maybe try to add the path before, adding a line like :

addpath(‘F:\data_fldtrp’)

Then you should be able to call your dataset with the first set of commands your wrote.
I hope this helps.
Alternatively, the second option you mentionned should also work, but the file you are calling is not the same in the two examples.

Best,
Éva

Objet :[FieldTrip] problem in importing my data in fieldtrip

Hello,
I am a novice in fieldtrip. Trying to learn it for my EEG analysis, on my own. I don't have any local group with whom I can discuss the problems I am facing here. I am trying to import continuous data into the fieldtrip for ft_preprocessing. Since I need to do ft_definetrial first for which I need to know the eventtype and eventvalues first, I tried calling ft_definetrial with cfg.dataset.
I gave the following command:
cfg = [];
cfg.dataset = '1_MD_1_edtd.set';
cfg.trialdef.eventtype = '?';
ft_definetrial(cfg);

But I am getting the following error:
Error using ft_trialfun_show (line 56)
file or directory '1_MD_1_edtd.set' does not exist

Error in ft_definetrial (line 199)
 [trl, event] = feval(cfg.trialfun, cfg);

I then tried specifying the filepath with the following command:
cfg = [];
cfg.dataset = 'F:\data_fldtrp\1_MD_1_epochs.set';
cfg.trialdef.eventtype = '?';
ft_definetrial(cfg);

But I am still getting the same error. How to write cfg.dataset = 'F:\data_fldtrp\1_MD_1_epochs.set'; so that fieldtrip can find the file?

Will be highly obliged if you can help me understand how to import data into fieldtrip.
Thanking you,
Moumita
