Hello Experts,

 

Hope you are well! I am trying to extract ROIs from the aparc+aseg file after running recon all however, I am getting the following result for all my images:

 

ciddrg@CIDDRGs-MacBook-Air C961060 % cd /Volumes/Akila/Cambridge/C961022 

ciddrg@CIDDRGs-MacBook-Air C961022 % isolate_labels.csh --vol aparc+aseg.nii --outprefix aparc+aseg_labels --L $label 7

Input file: aparc+aseg.nii

Output prefix: aparc+aseg_labels

mri_convert aparc+aseg.nii aparc+aseg.nii.gz 

reading from aparc+aseg.nii...

Could you help me with where the error might be? I would really appreciate your help, thank you!
