That's very unlikely to be due to MRtrix per se, but with some bug in the GTK or FreeType libraries installed on your system. My suggestion would be to try different versions of these libraries. </div>

Hi.<br>
<br>
I have a problem with mrtrix viewers. Everytime I am trying to start mrview (and all other mrtrix displays) on my computer (Mac OSX 10.6.8), I got a segmentation fault and nothing appears.<br>
<br>
I installed all the required software using Macports without any problems. I also checked the latest OpenGL version on my system: OpenGL 2.1.<br>
<br>
Those are the required installed ports:<br>
glib2 @2.38.2_0+universal<br>
glibmm @2.38.1_0<br>
libpng @1.5.17_0+universal<br>
gtk2 @2.24.22_0+universal+x11<br>
gtkmm @2.24.4_0+x11<br>
gtkglext @1.2.0_8<br>
gsl @1.16_1<br>
pkgconfig @0.28_0+universal<br>
<br>
I already tried to debug mrview using gdb as already suggested in your mailing list (see the attached logging file).<br>
<br>
Are there any further requirements or other ideas?<br>
<br>
Thanks in advance.<br>
