[Eeglablist] Please: need help with EEGLAB

[Makoto Miyakoshi]

Dear Nahla,

> I've checked the bug list and I found one (819) that have the same error but I am not sure if is due to the same problem that I have.

Very good.
What is your channel 31? EOG or ECG? Check if Ch31 has the same
structure as other EEG channels do.
