[Eeglablist] Editing eventcodes in eventlist

[Rebecca Geiselmann]

Hello everybody, 

I would like to edit the eventcodes in the eventlist created by ERP lab. 
In my case the most efficient way seems to be: saving the eventlist as a .txt. file, changing the event codes in the .txt file and uploading/applying the edited version. 

Nevertheless, I am facing several problems on the way (both using the GUI and a script) 

1) Using the GUI: 
	When I upload the edited eventlist under ERP lab - Eventlist - Create EEG Eventlist - Advanced, it shows an error message saying: 'There is one or more invalid eventcode entries’.
	
2) Ideally I would like to edit the eventlist using a script.
	However, using a script, I cannot figure out how to save the eventlist as a .txt file (not a .set file) and how to convert the edited .txt file back into a .set file.
	I tried to make use of ‘ERP.history’.  Nevertheless, this command unfortunately shows the following error message: ‘Dot indexing is not supported for variables of this type.’ 

Thank you very much in advance for your help. 

Kind regards, 
Rebecca
