How to save brain structural edited masks (segment edited) in nifti for freesurfer use?

Hi! I automatically generated structural brain masks with the purpose of using FreeSurfer. The masks need some editing, and I used Slicer Segment Editor for it (opened mask as label > imported labelmap as segmentation > add T1 as master volume > edited masks). However, I couldn’t save it as a nifti, so I saved as nrrd and later converted it to nifti. It didn’t work. How can I save my edited mask (in nifti) in order to use them for freesurfer? Do I have to convert the labelmap in something else?

Thanks!

You can use the Export to file feature in Segment Editor module. NIFTI export is available in the current Slicer Stable Release.
