[FieldTrip] distorsion of .edf file

[lucia abbatantuoni]

Hi Jan-Mathijs,
the specifies that you asked to me, are: 

fieldtrip version: 20130401
operating system: windows 7
matlab version : I use R2011a (64bits) or R2007b (32bits)

I
 want to read a portion of my EEG signal of 3600 sec * 500 Hz. When I used
 a previous version of fieldtrip (2011-12-14), the lenght of the window wasn't 3600*500 but less. 

" Warning: Integer operands are required for colon operator when used as index 
> In read_edf at 348 "

With fieldtrip 20130401 the length of the window is right, but, when I plot the signal, I can see its distorsion.
Thank you for your attention,
Lucia

Hi Lucia,
Perhaps you need to be a bit more specific. In particular with respect to the fieldtrip version, matlab version, operating system, and warning message.Otherwise all of us are shooting in the dark.Best wishes,Jan-Mathijs

I have the same problem.

if you want to read your data. it's possible to use ft_read_data(filename')

Dear all,
I'm analyzing EEG files in format .edf with matlab. Many files after the use of read_edf, have a distorsion. Matlab indicate a warning for the 348 row of read_edf . Can someone give to me a help?

Best regards,
Lucia
