Dear Dr. Litvak,

I am a phd student of Dr. James Kilner.

I have problem converting MEG data from fieltrip format to SPM8 format. I have already converted time frequency fieldtrip data without having any problem. I am now trying to convert data after running on it the ft_timelockanalysis function in fieldtrip. I get the following output error:
SPM8: spm_eeg_convert_ui (v3059)                   10:17:07 - 01/10/2014
========================================================================

SPM8: spm_eeg_channelselection (v2866)             10:17:21 - 01/10/2014

    S = spm_eeg_channelselection(S);
 
??? Error while evaluating uicontrol Callback

I added the BIOSIG toolbox to the path, but then the SPM GUI didn't work.

Do you know what I should do?

Thanks a lot

Myriam
