Hi Srishti
tksurfer has been deprecated for a pretty long time now. Can you try
freeview instead?
cheers

External Email - Use Caution
Hello,
I am trying to view network based maps produced from a meta-analysis using
neuroelf on the surface
in freesurfer. The meta-analytic maps are thresholded maps that represent the
proportion of
contrasts that activated at each voxel
I projected my maps on the surface using:
mri_vol2surf --src negative_allsocial_proportion.img --regheader mni152_subject
--hemi lh --o
./neg_allsocial_lh.nii --projfrac 0.5
Then to view it used:
tksurfer mni152_subject lh inflated -overlay ./neg_allsocial_lh.nii -fthresh
0.05
The issue I have is with the fthresh value. I read the wiki and some stuff on
archive about the
fthresh value but I am unsure what it exactly means and does. My issue is that
the display of my
maps changes when I change the fthresh value even though the maps have been
k-thresholded using
neuroelf before exporting them to freesurfer. More area is marked up when I
decrease the threshold
value from 0.1 to 0.05 and nothing is visible above 0.1
Does anyone have any thoughts about what might be going on there and how I can
fix it?
Do I need to do something totally different from what I am doing?
Best,
