When specifying the configuration of clusterstatistic, there are the options 'maxsum', 'max', 'maxsize' and 'wcm'. There seems to be no explanation of the 'wcm' option in the documentation that I can find, except that the option needs an extra cfg.wcm_weight.<div>
<br></div><div>I am assuming that wcm means weights cluster means, and that the cfg.wcm_weight is used to specify priors about sensors/time/frequencies of interest. However, it is not clear what this cfg.wcm_weight should look like, which dimensions it should have and how the ft_freqstatistics treats those weights.</div>
<div><br></div><div>It would be great if anyone could clarify this weighted cluster means. Assuming that I'm looking for effects in the data that might be quite focal in the time-frequency dimensions, would a weighting of ones (so equal weighting for all time and frequency points) pick up more clusters even if they are not very big in the time-frequency space?</div>
