[Eeglablist] eeg_checkset error when importing CNT

[Stephen Politzer-Ahles]

Hi Michael,

Thanks for the explanation. I just tried that out and it worked for me as
well (I had missed it before because when I clicked 'cancel' once the
warning would just pop up again... but just now if I clicked 'cancel' over
and over again then eventually it would load the data, and like you said
the error went away once I selected all but the last point). So now I am
able to import the data.

Of course, having to 'cancel' and select data means that data import for
multiple subjects can't be automated when I'm using that procedure... I
suppose that's not a huge problem, since I can at least import the data
manually, but being able to automate it would be quite helpful. I wonder if
anyone else on the list has experienced this error?

Thanks again,
Steve Politzer-Ahles
