Hi experts, 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 tkregister* But 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, Redwan
