[Eeglablist] Error using FMRIB 1.21

[Makoto Miyakoshi]

Dear Martina,

I would like you to try the following:

EEG.data = double(EEG.data);

Does this work? If so, maybe you need to load the data *after* changing the
single/double option.

Sorry for inconvenience. I'll appreciate if you can also file your report
to EEGLAB bugzilla
