Hello,
I want to import an event list file that was previously calculated based on button presses in Matlab to analyse ERPs in ERPLAB(EEGLAB Toolbox) due to experimental setup, but I couldn't figure out how to import them to EEGLAB.
When I import the sample tutorial events(https://sccn.ucsd.edu/eeglab/download/tutorial_eventtable.txt), I always get the error message you can find in the attachment.
I would like to be able to import the events list as an m file and it would be really helpful if I could find an example of an event file in m file format.
I would be very grateful if anyone could help me figure out the cause of my error message and help me get an idea about the appearance of the m event file.
I appreciate your help in advance.

Dear Demet Yeşilbaş
Hope this massage finds you well. Instead of using your file which you have shared the link of it in .m file or .txt file utilize .xlsx format in Excel file. I have reshaped your data in an Excel file which is attached to this massage.
Use bellow command to read Excel files in MATLAB :
For example if you want to import an excel file titled "excel_file2.xlsx" put in first array them put a comma. After that mention the sheet name and then in third array define columns and rows. In bellow command we want to read A2 to B16 range ( columns and rows ).
B = xlsread('excel_file2.xlsx','Sheet2','A2:B16')

Dear Hossein Safar Yousefifard ,
Thank you very much for your answer and time, but I am not sure how your answer would help me.
I would like to be able to use ERPLAB in the EEGLAB toolkbox, which help studying the electroenceophological signals of the brain, but don't know what the appropriate event file should look like in order to import the stimulus start time points which was recorded and calculated outside the EEG file in the experimental setup.
Best wishes,
Demet
Dear Demet Yeşilbaş
Commonly you could import.mat, .xlsx, .CSV and so on in most of MATLAB Toolbox so you don not have any limitation with file format and you can easily import it to MATLAB using mentioned Command. Also if you want to import some special columns and rows ( not all of them ) , you could define them in above-mentioned command.
Usually appropriate file format is .mat for importing time series data and their values but because your data are not very big and it has less dimension. So, it is okay to use excel file but if you want I can change it to .mat file which is readable for all of MATLAB Toolboxes.
Warm Regards,
Hossein
