Hi FS experts,

I just installed 5.2 for Snow Leopard in a machine who already had 5.1. 

When running tkmedit in 5.1 X11 works well, but when running it from 5.2 it gives the following error: 

BRODMANN80:~ glerma$ tkmedit bert T1.mgz

dyld: Library not loaded: /opt/X11/lib/libGLU.1.dylib

  Referenced from: /Users/glerma/Apps/freesurfer/tktools/tkmedit.bin

  Reason: image not found

Trace/BPT trap

I've seen in  the mail list that when this happens, Xquartz should be installed. 

But, is it a requirement for freesurfer 5.2 in Snow Leopard to run with Xquartz? Should I remove X11 and install Xquartz then? (it may affect other programs and I am reluctant to do it...)

Many thanks,

Gari
