Hi Sophie,
<div class=""><br class="">
</div>
<div class="">Currently I have a script that manually does what you are suggesting. Basically, this script identifies where in the massive array of 0’s a cluster exists in the posclusterlabelmat matrix, then it aligns this with the respective freq, time, and
channel files to isolate at which points this effect is occurring. I should have clarified better though as I was wondering if this has already been programmed into field trip. Is there a field in my structure or a certain function one can call upon that would
extract this information more easily? Currently this takes substantial manual heavy lifting/programming experience to get this information. </div>

Next to your postclusterslabelmat field your structure should also contain a dimord field which tells you what the dimensions relate to for example a dimord: 'chan_freq_time' tells you that the first dimension of your posclusterslabelmat is the channel dimension,
2nd one frequencies etc... And then you have to compare with the respective fields 'labels', 'freq' and 'time' to know what the indices refer to exactly.<br class="">

<div class="">Greetings,
<div class=""><br class="">
<div class="">I am inquiring about the most efficient method for identifying the time, frequency, and channel information for each cluster identified as significant by the permutation analysis. I currently have three clusters in my posclusterslabelmat structure,
but am curious about which time points, frequencies, and channels these clusters correspond to. Any advice or assistance as to how this information can be extracted from Fieldtrip would be greatly appreciated.</div>
