Dear Makoto,

First of all it's my fault for not being specific with my question.

When i open the Channel Location windows, it was supposed that the function
will automatically look up channel locations for these known channel labels
and when i pressed the Look Up Locs button, nothing happened
i'm working on this dataset if that helpful

Best.
