[Freesurfer] Problem launching qdec.

Hi,

I have two questions:

1) I just upgrade our intel Mac OS from Tiger to Leopard, and now are having problem using qdec. I am using version 4.0.0. When I type qdec in xterm, it outputs the following error msg:

dyld: Library not loaded: /usr/X11R6/lib/libexpat.0.dylib Referenced from: /Applications/freesurfer/lib/KWWidgets/lib/KWWidgets/libKWWidgets.dylib Reason: image not found Trace/BPT trap

Any idea how to fix this?

2) We have done the editing on 300 subjects (pial, wm and control point) and re-generated all the surfaces. One thing I realized is that the aseg.mgz does not follow the surfaces as it is processed before the surface reconstruction. Is there any way to re-generate the aseg.mgz using ?h.pial, ?h.white?

Thanks, Zheng Hui
