I do not know what kind of script you wrote, therefore, it is difficult to figure out what the problem is exactly. But your problems reminds me to the following:<br>
if you followed the FT tutorial for plotting the clusters, you must be aware that it will plot only those channels in each time-bin that are part of the cluster during the entire time-bin. So, if you use a 50 ms bin, and a channel is part of the significant cluster only for 10 ms, you won't see that channel on the plot. I hope this helps.<br>
<br>
Best,<br>

Sorry, I know the answer now, but I have another , similar problem:<br>
<br>
When i get the clusterplot figure (after i run the cluster analysis), it has the timebins every 4ms (bc i have a 250Hz sampling rate) with the significant clusters plotted. For a simplified plotting, i was trying to use the bit of script where i can specify the timesteps i want the clusters to be shown in (ex: every 50ms)<br>
But, depending on what timestep i use, sometimes it does not display the clusters that are significant, almost like if the period is not long enough, it will not show the clusters...<br>
<br>
Any ideas ?<br>
<br>
Thank you!<br>

Dear All<br>
<br>
I am running the Cluster-based permutation tests on event related<br>
fields, and for the same dataset, with all settings identical, when<br>
i run:<br>
0-200ms: i get one significant cluster<br>
but:<br>
0-500ms: no significant clusters<br>
<br>
why does my significant cluster disappear depending on the time<br>
window i use?<br>
<br>
thank you!<br>
