Hello Everyone!
I have several structural
images were too much dura was included into the wm calculation. (see
recon-all_std for the standard processing image)
I followed the
skull strip instructions
and the gcut procedure made only minor changes, and so I used the
watershed and lowered the threshold it removed the dura, but did not
update the .pial files to match the updated edge.
This is output to screen and command that I usedrecon-all -skullstrip -wsthresh 20 -clean-bm -subjid 31313422_15544
