tksurfer has some instabilities in it. It is obsolete and no longer being supported. Have you tried freeview? You can use tksurferfv which runs freeview with tksurfer options.

Hello all,

I have been using freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c on macos high sierra, then I updated to mojave 10.14. freeusrfer was working all good for a while. BUT, for unknown reasons, I am no longer able to overlay the significance maps using tksurfer and cant open qdec, like below:

command: tksurfer fsaverage lh inflated

output error: subject is fsaverage hemi is lh surface is inflated surfer: current subjects dir: /Users/wsweidan/Desktop/GLM_trial surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /Users/wsweidan/Desktop/GLM_trial checking for nofix files in 'inflated' Reading image info (/Users/wsweidan/Desktop/GLM_trial/fsaverage) Reading /Users/wsweidan/Desktop/GLM_trial/fsaverage/mri/orig.mgz surfer: Reading header info from /Users/wsweidan/Desktop/GLM_trial/fsaverage/mri/orig.mgz surfer: vertices=163842, faces=327680 surfer: single buffered window surfer: tkoInitWindow(fsaverage) setting percentile thresholds (-1.00, 0.00, 0.00) surfer: using interface /Applications/freesurfer/tktools/tksurfer.tcl Reading /Applications/freesurfer/tktools/tkm_common.tcl Reading /Applications/freesurfer/tktools/tkm_wrappers.tcl Reading /Applications/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /Applications/freesurfer/tktools/tkUtils.tcl Error sourcing /Applications/freesurfer/tktools/tksurfer.tcl: bad distance "0.125i": can't be negative reading white matter vertex locations... % Floating exception

command: qdec output error: Floating exception

I reinstalled freesurfer again and I still get the same errors. Freeview works just fine. Any input of how to solve this issue?

Thanks in advance, Wafaa
