I am trying to import data from Pure Eeg software to Eeglab in edf format but i have problem.
First, i tried to import the edf file (FILE->Import data->Using EEGLAB functions and plugins->From EDF/EDF+/GDF files(Biosig Toolbox)) but an error occured “Unsupported data format, (Error occured in function pop_biosig() at line 89).
Also, i tried to open with edfbrowser “Error, header has unknown version:”20160817”,expected “0” File is not valid EDF or BDF file. Someone with the same problem in Egglab mailing list reccomended to use this program https://github.com/Emotiv/community-sdk/tree/master/tools/EEGLAB_EDF_FIXED/EdfHeaderConverter. I tried it but i think i have problem again.
After some warnings in matlab window : “Warning SOPEN (EDF/BDF): filesize (4219136) of E:\converted\ba520fbc-f0bb-491a-a06c-f1801dc6f196.edf does not fit headerinformation (NRec = 414 not 411).” the eeglab window ( Load data using BIOSIG–pop_biosig() )opens . If i am trying to write channel list[3,4,5,6,7,8,9,10,11,12,13,14,15,16] an error occurs : “EEGLAB error in function biosig2eeglab() at line 67. Index exceeds matrix dimensions.”
When i dont write in the field channel list , it seems to open the edf file with all channels by default. The epoc end in seconds is: 410.992 but the duration of my recording is 6:54 minutes, 392.4 seconds. I think something is wrong.
Do you have any ideas?
Thank you for your time…
