what is your tksurfer command line? Can you send all the terminal output from tksurfer? Does it work in freeview?

Hi,
I’m trying to take an ROI in MNI152 volume space and make it into a cortical surface label, for visualization purposes.
With my input being the lh thresholded, binarized MNI152 nii.gz label (when I visualize it, it looks as it should in fslview), I ran:
mri_vol2vol -- mov <labelinput.nii.gz> -- targ $SUBJECTS_DIR/fsaverage/mri/orig.mgz -- o <outputname.nii.gz> -- regheader -- talres 2 -- interp nearest
mri_cor2label -- c <outputname.nii.gz from above> -- id 1 -- l ./<newoutputname.label>
My commands above seem to have run fine, but when I open the lh in tksurfer and try to load the new lh label file, the dialogue runs for a little but then errors out:
12304 unassigned vertices in label - building spatial LUT… assigning vertex numbers to label... MatrixMultiply: m2 is null!
And then tksurfer closes. I’m not sure what’s going wrong - does anyone have any pointers or troubleshooting methods I can try?
Thanks, Stephanie
