Really sorry for the long post. I am a new MRTrix user from UMass trying to visualize DTI data from patients in a mindfulness study. I have a brand new IMac Pro machine which should support up to OpenGL 4.1. I installed MRTrix through homebrew per https://mrtrix.readthedocs.io/en/latest/installation/mac_install.html , including QT and other dependencies, and my MRView seems to open a blank window with no tools or images (I tried structural, functional, and DTI .nii and .mif files).
Several troubleshooting steps I’ve taken was to create an mrtrix.conf file in my /etc/ folder with:
Which then instead of launching MRView as a blank screen will then crash with errors:
mrview: [WARNING] unable to determine OpenGL version - operation may be unstable if actual version is less than 3.3
mrview: [ERROR] GLSL log [vertex shader]: ERROR: 0:1: ‘’ : version ‘330’ is not supported
ERROR: 0:1: ‘’ : syntax error: #version
ERROR: 0:2: ‘layout’ : syntax error: syntax error
mrview: [ERROR] error compiling OpenGL vertex shader ID 1
mrview: [SYSTEM FATAL CODE: SIGSEGV (11)] Segmentation fault: Invalid memory access
My QT version is 5.12.0 . Also, per: openGL problem with mrview on Mac OSX I ran (pasted into my command line directly):
Which didn’t seem to change anything.
I’m really frustrated and at my wit’s end, so any advice is appreciated. Thank you!
