I try to convert my volumetric nifti file to surface files.
My nifti volumetric file looks like : 1. screenshot
I have first registered the volumetric file using bbregister with this command line :
bbregister --s fsaverage --mov segment_7.nii --reg segment_7.dat --t1 --init-coreg
then I have used the following command line and the file looks like screenshot 1 attached :
tkregister2 --mov segment_7.nii --reg register7.dat --surf
And after that, I have tried to convert my volumetric file to surface file with this command line :
mri_vol2surf --src segment_7.nii --srcreg register7.dat --hemi lh --o ./segment_7-lh.nii --float2int round
But with this command when I load the file with freeview it does not work and with tkregister the file is empty.
Or this one :
mri_vol2surf --src segment_7.nii --srcreg register7.dat --hemi lh --o ./segment_7-lh.w --out_type paint --float2int tkregisterBut with this command I have this warning :
Warning: all vertex values are zero
Could you please help me to convert my volumetric files because I am probably doing someting wrong. All my files come from an Atlas and I just need to convert them to surfaces files.
Thank you for your help,
