If you are trying to export a complex Fieldtrip dataset, you may be creating unecessary issue.

<br>
I have done preprocessing of my data with Fieldtrip and would like to load it into EEGLAB.<br>
<br>
At first I have tried to load it as matlab file, but got this error:<br>
<br>
pop_editset(): raw data file 'E:\Matlab_code\new pipeline\neglect\1_AM_data_<wbr>pICA_clean.mat' found<br>
eeg_checkset note: upper time limit (xmax) adjusted so (xmax-xmin)*srate+1 = number of frames<br>
Creating a new ALLEEG dataset 1<br>
Done.<br>
Undefined function 'isnan' for input arguments of type 'struct'.<br>
<br>
Error in eeglab>updatemenu (line 1560)<br>
if ~isempty(ALLEEG) & CURRENTSET~= 0 & ~isequal(EEG.data, ALLEEG(CURRENTSET).data) & ~isnan(EEG.data(1))<br>
<br>
Error in eeglab (line 368)<br>
updatemenu;<br>
<br>
Error while evaluating Menu Callback<br>
<br>
So I have tried to use the function fieldtrip2eeglab, but I am probably making some mistakes because this is what happened:<br>
<br>
Undefined variable "data" or class "data.trial".<br>
<br>
Error in fieldtrip2eeglab (line 20)<br>
for i=1:size(data.trial,2)<br>
<br>
Do you have any idea about what I'm doing wrong or do you have any suggestions?<br>
<br>
Best,<br>
Federica<br>
