External Email - Use Caution
He¹s probably got some clinical software that only accepts DICOMs. While converting volume files back to DICOMs is possible, I don¹t know if that is something FreeSurfer supports. You might need to find another tool to do that conversion.

I'm not sure what you mean by "what my system will further deal with". You could extract slices I suppose, but typical MRI acquisitions that are highres are volumes. The brainmask.mgz will be volume as will everthing else in the mri dir

External Email - Use Cautionok so after the recon-all command runs, in the output directory's mri folder, a file called brainmask.mgz is formed. I have been doing a freeview -v of this file which corresponds to the final skull stripped output for my input slice that I wanted. Now as per the information that you gave me, I should have a volume. This leads me to two questions. How do I access the volume, where is it in the folder ? And how to I get slices again from this volume because originally I had slices and slices is what my system will further deal with.
