[Eeglablist] Problem with Plotting Channel Spectra and Map

[Makoto Miyakoshi]

Dear Donia,

Other causes I can think of are, Matlab and EEGLAB versions, toolbox
dependency (which is unlikely in this case), invalid enter to the channel
location info, etc... Could you share the screenshot of one of channel info
with us?
