I don't know anything about neuroelf, but unless your have a binarized
map, then the map is going to change when you change the threshold. BTW,
if you wan to use freeview, you can run tksurferfv with the same args as
tksurfer

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?
