Hi everyone, I was hoping that someone could clarify for me the role played by norm.mgz in the command
mri_pretess filled.mgz 255 norm.mgz filled-pretess255.mgz from the -tessellate step of the -autrecon2 section on the page http://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable. My understanding is that this command will (roughly) perform the following tasks for a given voxel v in filled.mgz with intensity 255: 1) Determine whether there are any other voxels of intensity 255 in the 3x3x3 cube centered at v. 2) If so, then further determine whether none of these share a face with v. 3) If so, then let S be the set of all such voxels, together with v itself, and identify an "optimal" collection of the remaining voxels in the 3x3x3 cube to add to S so that every voxel in S shares a a face with at least one other voxel in S, where "optimal" means that the added voxels should have intensities as close as possible to 255 in norm.mgz. Does this capture the role played by norm.mgz? Or am I way off? Thanks in advance for your help, David Romano
