[FieldTrip] ft_clusterplot vlim error

[G Stothart]

Hi,
I am trying to plot the outcome of a cluster analysis of a 
within-subjects time frequency analysis.


cfg = [];
cfg.layout = 'acticap32.mat';
cfg.alpha  = 0.05;
cfg.parameter = 'raweffect';
ft_clusterplot(cfg, stat);

I keep receiving an error message referring to vlim, but I can't seem to 
solve this.Specifically I get the following output from matlab:

reading layout from file acticap32.mat
the call to "ft_prepare_layout" took 0 seconds
There are 1 clusters smaller than alpha (0.05)
Positive cluster: 1, pvalue: 0.049505 (x)
the call to "ft_prepare_layout" took 0 seconds
Warning: The option cfg.xparam is deprecated, support is no longer 
guaranteed

As requested here are the cfg and stat details.

 >> display (cfg)

cfg =

        layout: 'acticap32.mat'
         alpha: 0.0500
     parameter: 'raweffect'

 >> display (stat)

stat =

                    prob: [33x1x25 double]
             posclusters: [1x9 struct]
     posclusterslabelmat: [33x1x25 double]
         posdistribution: [1x100 double]
             negclusters: [1x3 struct]
     negclusterslabelmat: [33x1x25 double]
         negdistribution: [1x100 double]
                 cirange: [33x1x25 double]
                    mask: [33x1x25 logical]
                    stat: [33x1x25 double]
                     ref: [33x1x25 double]
                  dimord: 'chan_freq_time'
                   label: {33x1 cell}
                    time: [1x25 double]
                     cfg: [1x1 struct]
               raweffect: [33x34x25 double]

I have attached my layout file (acticap32.mat), my cfg and stat files.
Many thanks!
George
