Hi James,
1. We don't have anything that does quite this, but if you run mri_average on the lh and rh volumes it should be good enough (you could run mri_binarize afterwards if you wanted).
2. What format are you outputting? If .mgz (or .nii) it should retain all orientation info, which you can look at with mri_info (or bring the volume up in scuba, using scuba -v <volume file name>).
cheers, Bruce

I am using mris_fill to create a volume from the lh.pial surface as well as the rh.pial surface. I have 2 questions:
- How can I combine the 2 separate hemisphere volumes into a single
full brain volume that I can export and view in analyze? I only know to use mri_convert on each one separately. Does this need to be done before I run mris_fill, or is there another combined surface that has the same resolution as the pial surfaces that I can run mris_fill on? 2. I know that when I run mris_fill, the volumes that are produced do not contain orientation information. When I load them into Analyze, the volume is mirrored and upside down. I was wondering how I can "get" orientation information back into the volume, and also correct the mirrored and upside down viewing issue.
These results were produced by Freesurfer from standard dicom files from a volumetric scan.
Thanks,
