Hi Erik
what is the dimensionality of sig.cluster.mgh? You can tell this with
mri_info. It is problaby a surface overlay (so nvertices in one dimension),
and can't be viewed in the volume but only on the surface.
cheers

Dear Douglas and Freesufers,
You suggested:
mri_binarize --i sig.cluster.mgh --min 1.3 --o thresholded.mgh 1.3 =
-log10(.05)
I tried this and was expecting that I would get a three-dimensional mask in
which the statistical significant part would be white and the rest black.
This seems not to be the case. While the program is telling me that it is
creating a mask in which x-number of voxels are included I cannot see
anything when I open the thresholded.mgh (in Freeview) Further when I look
at the dimensions of the generated image it seems to have 27307 “slices” in
one direction but only one and 6 slices in the other directions.
Is this the wrong approach for creating a 3-dimensional mask for the region
with the significant clusters?
Best
Eric
