Hi Doug, Thanks for your help. A followup question to your last email: the short term fix that you mentioned earlier, do I need to make that fix in addition to copying the new mri_surfcluster file in the binary dir? Or has that been fixed already? Thanks, Devdutta On Mon, Mar 9, 2009 at 4:41 PM

Try copying this: ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surfcluster into your $FREESURFER_HOME/bin directory (make a backup first), and then re-run. doug Devdutta W wrote: We are using Red Hat Enterprise Linux 5. Thanks for your help. I'll try that out. On Mon

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? doug Devdutta W

When I load mc-z.abs.2.sig.cluster.mgh, if the "Draw filled labels" button is toggled on, it looks no different from before. Toggling the "show overlay" button doesn't do anything. If the "Draw Outlined labels" button is toggled on, the outlines of the colored regions can be seen (including the ou

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

Hi Nick, Can you shed some light on why this might be happening? I will attach the two picture again in case you weren't able to view them last time. I tried what I thought you meant by "turn off annotation display" and I have stated what happened in my previous email (please see below) - *If

Nick, I confess, I am not exactly sure what you mean by "turn off annotation display". I tried a few things. - If I don't include the -annot option in tksurfer it only displays the fsaverage, naturally. - If I toggle off the button that says "show labels", it looks like it is just

What is displayed if you turn off the annotation display? The threshold in the simulation is used to determine whether clusters are found or not. A threshold of 2 indicates a p-value of 0.01 (1/(10^2), 3 is 0.001, etc. The threshold referred to in the tksurfer display is just for color threshold
