Dear freesurfer experts,

We have some files containing the values for regions based on the Deskian/Killiany atlas like :

ROI, value

'lh_bankssts', .9

'lh_caudalanteriorcingulate', .1

'lh_caudalmiddlefrontal', .5

'lh_cuneus', .2

'lh_entorhinal', .5

'lh_fusiform', .9

'lh_inferiorparietal', .7

And we have the information on the labels in Matlab data format:

I wish to create a surface file (.nv or .pial) based on the atlas and values which can be visualized directly in software like BrainNetViewer.
We are also considering to visualized the brain images with SurfStat which needs a .obj file and .txt file:
s100 = SurfStatReadSurf( {...
'c:/keith/fMRI/ICBM/surfaces/mni_icbm_00100_mid_surface_left_81920.obj',...
'c:/keith/fMRI/ICBM/surfaces/mni_icbm_00100_mid_surface_right_81920.obj'} );

t100 = SurfStatReadData( {... 'c:/keith/fMRI/ICBM/thickness/mni_icbm_00100_native_rms_rsl_tlink_20mm_left.txt',...
'c:/keith/fMRI/ICBM/thickness/mni_icbm_00100_native_rms_rsl_tlink_20mm_right.txt'} );

SurfStatView( t100, s100, 'Cort Thick (mm), Subj 00100' );

But I have no idea how the .obj file is created and how the .txt file should be organized.

Is there any way to make it?

Thanks in advance!

Best,
Xin
