Hi,<br>I have been following the documentation for mri_glmfit-sim and need a bit of clarification.&nbsp; The point where we run tksurfer with the -annot option, it seems that it displays all the clusters (regardess of the significance) on the average brain.&nbsp; When I run it, it looks like cortical parcellations are being displayed on the brain.&nbsp; It also displays the clusters (within the parcellations); so it seems to be working.&nbsp; I am just curious as to why the parcellations are being displayed.&nbsp; Here is the command I am using.<br>

<br><i>tksurfer fsaverage rh inflated -annot mc-z.abs.2.sig.ocn.annot -fthresh 2 -curv -gray</i><br><br>But more importantly, I would like to know how to interpret what I am seeing correctly.&nbsp; I understand that the p-value threshold can be set by -fthresh (2 corresponds to p value of 0.01).&nbsp; In the cluster summary (it found 25 clusters), I am seeing CWP of 0.001 for 24 of the 25 clusters.&nbsp; What does this significance mean as calculated by the command?&nbsp; Is this corrected across the whole brain?<br>
<br>Thank you,<br>Devdutta<br>
