[Eeglablist] Why does basic filter gives an error in one particular dataset, but not in the others?

[Roi, la, A.]

Dear Andreas and Arnaud,

Thank you for your reply. I wasn't sure whether to report this problem to
the EEGLAB mailing list or the ERPLAB mailing list, but now I know.

Kind regards,
Amélie la Roi
