[Eeglablist] problems importing neuroscan .cnt with trigger information

[Jordi Costa Faidella]

Thanks a lot Gabor, that really helped! I didn't imagine it had been such an easy thing to solve.
Greetings from NYC, soon back in Barcelona...

ps:Toomas, I've been using eeglab only with neuroscan data and never had such a problem you say. I've used it under Windows (32 and 64-bit), Mac and Linux. My Matlabs have been 2008b, but I don't think using 2010 will make any difference. Have you checked if the 16 or 32 bit option when importing the data fits with the data you acquired? Hope this helps... I get nice continuous data, ERPs, TFs, and whatever I do...

It is the first time I'm doing an experiment in which the participants need to give an answer by pressing a button, so never before I had to face this issue. The trigger for the answer appears in the .cnt file while recording it, while viewing it with neuroscan software and when extracting the .evt or .ev2 files. However, when I import the .cnt into eeglab, those triggers coding the participant's answers are missing. If I try to import the .cnt and then an .ev2 file eeglab gives me an error. However, I wouldn't like to depend on neuroscan software, and as long as the trigger information is in the .cnt file, there should be a way to import the .cnt into eeglab with the information of all triggers. Does anyone faced this problem before? I would be very pleased if someone could help me or post some written script to solve this issue.
