Hello
we want to do T depandent statistic over group of subjects with two 
conditions to find time -space cluster for Loreta's output.As you advised 
we used a monte carlo method as in attached file.We use one person's data
and low number of rundomization to simplify function .
WE got error message :

"
??? In an assignment  A(:) = B, the number of elements in A and B
must be the same.

Error in ==> fieldtrip-20061202\private\clusterstat at 111
    tmp(cfg.inside) = postailobs;

Error in ==> statistics_montecarlo at 308
  stat = clusterstat(cfg, statrand, statobs);

Error in ==> fieldtrip-20061202\private\statistics_wrapper at 233
  [stat, cfg] = statmethod(cfg, dat, cfg.design);

Error in ==> sourcestatistics at 112
  stat = statistics_wrapper(cfg, varargin{:});%
***********************monte here

Error in ==> try1 at 25
stat = sourcestatistics(cfg, cond1{:}, cond2{:});  "

Can you help us? 
sincerely
