[Freesurfer] subcortical roi

Dear FS experts, I run recon all on several patients, manual edited all the outputs and rerun recon all. I'm interested in subcortical segmentation and I extracted all the data with the aseg stats command. Is it now possible to select a structure (let's say the accumbens) and save it as a .nii (or wathever format) ROI in ordero to export it and open it with other softwares (e.g. mricron, fsl etc)? thank you in advance Fabrizio Piras --------------------------- Fabrizio Piras Ph.D. --------------------------- Fondazione I.R.C.C.S.
