I think I've found the problem in that the original annotation at a
vertex is not being cleared if a cluster is not there.
The short term fix is to delete " --annot aparc" from mri_glmfit-sim at
line 353. I'll email when I have a longer term fix. What platform are
you using?

If the "Draw Outlined labels" button is toggled on, the outlines of
the colored regions can be seen (including the outlines of the
clusters). This time, toggling the overlay button on-off shows the
clusters.

Nick, Sita,
The average subject is created from our data, perhaps that's
why it looks different. We were having problems getting
freesurfer to recognize our average subject. So we linked
fsaverage to our average subject. I didn't see a button (or a
tool) to toggle on-off the annotation. The overlay button is
there but toggling it doesn't do anything.
There indeed are clusters mixed in with the annotations. But
from the documenation, it seems that the command we are using
is /supposed/ to show clusters (but only the clusters, not the
the annotations). And that is the question I am trying to get
answered.
Here is the command we are using:
/tksurfer fsaverage lh inflated -annot
mc-z.abs.2.sig.ocn.annot -fthresh 2 -curv -gray/
I am running this command from the appropriate folder and
fsaverage is linked to our average subject. We are using the
following documentation:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis?highlight=(mri
<https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis?highlight=%28mri>
<https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis?highlight=%28mri>\_glmfit\-sim)
Thanks,

Devdutta,
What version of freesurfer is being used? The fsaverage
subject you
show doesnt look right. Also, I see what appear to be clusters
mixed in
with the annotations. The summary files output by the multiple
correction step will tell you how many and the size of the
clusters.
You should be able to toggle on-off both the annotation and the
overlay
independently.
I am cc'ing Sita, as she may be able to help you on this (I
will have
limited email contact this week).
