[FieldTrip] Cluster-based permutation test (CBPT)

[Johanna Zumer]

Dear Jose,

It appears from lines within the error message that you are using Fieldtrip
version 20140311.  Is that right?    If you update to the latest version,
do you still get the error?
Also, what version of Matlab are you using?

Kind regards,
Johanna
