Hello everyone!
This is my query:
> We have two groups of EEG data (recorded in a 'Delayed Match to Sample task') pre-processed with Matlab and EEGlab. Each group is a matrix (.mat) which has 3 dimensions (channels x time x subjects). At this point, we are interested in apply the Cluster-based permutation test for nonparametric tests (Maris and Oostenveld, 2007) in order to find out the possible significant differences between these two groups on the different event related potentials.
>
> The question is wether we have the possibility to apply this non parametric test, using field trip, EEGLAB or any other software, on this EEGLAB pre-processed matrix data (.mat); or, on the other hand, we have to start from the raw data (recorded with ASA (.cnt)) and go through all the necessary steps indicated on the methodology of the Cluster-based permutation test.

> Thank you very much.
