[Eeglablist] Eeglab - Negative polarity up

[JIMENEZ, MIKEL]

Dear all,

I'm trying to plot my EEG data sets with the negative polarity up (on Channel Data Scroll, for example) but I cannot make it happen.

I have read a couple of similar questions, apparently by changing the YDIR option in the "icadefs.m" file to -1 would do the trick. However, when I change this option nothing happens.

Would anyone know about this? Any help would be very much appreciated.

Thanks,
Mikel
