[FieldTrip] Preprocessing and analysis of spike and local field potential data - issue with calling certain functions

[Thomas Wunderle]

Hi all,
I put that bug already two weeks ago into the bugzilla, see

http://bugzilla.fcdonders.nl/show_bug.cgi?id=2641

You can add the line

'progress'

in ft_checkconfig to make it work again.

Best,
Thomas
