Hi Douglas, Thank you for your help,
So I still can't convert my volumetric file to a surface file and I don't know what I am doing wrong. My nifti volumetric file looks like : 1. screenshot As you said, i have first registered the volumetric file using bbregister. I have used this command line : tkregister2 --mov segment_7.nii --reg register7.dat --surf (knowing that segment_7.nii is my volumetric file which looks like 1.screenshot). With this command line, my output is this file : 2.screenshot (attached). Am I satisfied with this file ? if not what can I do to improve the result and the matching ? 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 Thank you by advance for your precious help, Have a nice day, Redwan On 1 March 2017 at 07:31, Douglas Greve <gr...@nmr.mgh.harvard.edu> wrote: > Hi Redwan, > > You'll need to register your volume to an FS-analyzed data set (probably > using bbregister).
