Hi Arti,
 For very focal effects, the tmax permutation test and Benjamini & Hochberg false discovery rate (FDR) control algorithm are more powerful than cluster-based permutation tests:

Dear list,
I was wondering whether it is appropriate to use cluster permutation tests on 32 channel ERP data. I am working on visual ERP response to text stimuli, and since there are only few electrodes I am expecting a focal effect (on P7 and P8). I was wondering whether it is appropriate to use cluster statistics here. If not, what test do you suggest?
Thank you,
Arti
