Hi Gallen,
I suggest that you extract the values across subjects at a single vertex
in fsaverage space, and then attempt to duplicate FS&#

Hi Courtney,
a couple of suggestions:
1. make sure that QDEC and SPSS are using the identical model.

Hi Courtney,
I'm no expert but I recalled a post similar to yours awhile ago with the same
question you ask. Doug and Nick offered an answer that may be of help:

Those are the values outside (first column) and inside (2nd col) the
ROI. You can add "--id 1" to only report the values inside the ROI.

If you run the cluster-based correction for multiple comparisons
(mri_glmfit-sim), it will create a table of clusters with their areas
and the average contrast in each cluster.

Hi,
I'm currently running analyses in Qdec and have identified areas that show
significant effects in my contrasts. I have two questions related to
interpreting these results.
1. How can you interpret the effect in each "blob?" (i.e., which group has
a greater cortical surface area, etc.)
