[FieldTrip] EEG txt files conversion to .Edf

[Maité Crespo García]

Hi Federica,
when you open the .txt file in notepad, does it have any additional information apart from numeric values? If yes, then you should try another Matlab function for importing the data. If not, then you should find out relevant information, such as sampling rate, time, the labels of the channels, the number of trials, etc. Then, you could build your own data structure inside Matlab and save this file as edf with Fieldtrip.

 Dear Sarang and Robert,

thank you for youe suggestions.

I've been working on them, but it seems that my main problem is I don't have an header for my data. And at the moment I don't have any clue on how to get it.

Basically, when I success in load the data matrix on Matlab, it has the dimensions of <5192001x5 double>, and this doesn't fit with any format recognized by Fieldtrip.
Namely, when I try to construct the header with 
 hdr = ft_fetch_header(data)

it says: Error using ft_checkdata (line 464)
This function requires raw data as input.

Error in ft_fetch_header (line 32)
data = ft_checkdata(data, 'datatype', 'raw', 'hassampleinfo',
'yes');

Thank you again for any suggestion.

Cheers,
Federica

Hi Frederica,

Hi Maité,
thank you for the suggestion. I don't have the access to BESA now, so I wished I could work it out with Matlab and related toolboxes.
Best regards,Federica

Hi Federica,
If you have access to BESA, you could import txt files and export them as edf.
Best,Maite
