I'm sure that those clusters are not very significant. Try running mri_glmfit-sim with --cwd .99 to capture all clusters doug

HI Doug, here's a screen shot, showing the clusters and a scatter plot for one of the 45 clusters. for this dataset, ussualy there is 0 or 1 clusters after monte carlo simulation. i'm not sure if they match one of the 45 clusters in qdec. i'l have to look into that.
I would like to have a file which contains the data represented in the scatter plot, for all of the 45 clusters, vlaues of thickness for each subject. is that possible? I tried runnin mri_surfcluster, but it only gave me the average data for that clusters, not the individual data.
thanks!

I'm not sure what is going on. Can you send a screen shot of the qdec window when you see 40 clusters? It might be that it is showing clusters regardless of the cluster significance. Do the 3 or 4 clusters created when you run mri_glmfit-sim match clusters in qdec?

which contrast are you looking at in QDEC? Also, what is the voxel-wise threshold in QDEC? The value I gave in the command below is 1.3 but I got that from one of your CSD files.

HI doug, no, the summary files in the contrasts have the same # of cluster as the columns in their OCN.dat \ the 40 cluster are seen in qdec when I run the "find cluster" and Goto max" button. most of these clusters go away in qdec when I run the montecarlo simulation

So one of the contrasts has 40 clusters in the summary file but the y.ocn.dat file only has a few columns?

There should be a column for each cluster in contrast. Is that what you want?
