[Freesurfer] Inconsistency in SI axis coordinate between FreeSurfer recon-all seg image and BrainVoyager

ordinate report in the SI axis. If this is the case, is this stored in freesurfer such that I can get coordinates relative to the uncropped image or just the offset value for the Z coordinate to compensate for it? Thanks, Jerry Jeyachandra __

surface normal vector from plial surfaceRAS coordinate We don't have a way to compute the exact distance from one vertex to another along the surface (working on it!). If the distances are small, then euclidian might work ok. On 05/10/2017 12:35 PM, Jerry Jeyachandra wrote: > > Hi Bruc

[Freesurfer] Cropping of slices during recon-all

2017-06-15 Thread Jerry Jeyachandra
Hi Freesurfer team, I have a compressed nifti file converted from DICOM that I am running through recon-all. From my understanding first mri_convert is run on the original nifti file in order to generate 001.mgz which is then averaged across multiple runs to make rawavg.mgz. Since I'm only usin
