Re: [Freesurfer] volume changes

To answer your question more completely, we're trying to compare two files with the following headers: Freesurfer segmentation: height = 256 width = 256 depth = 256 nframe = 1 imnr0 = 1 imnr1 = 256 xnum = 256 ynum = 256 fov = 256.00 thick = 1.00 xstart = -128.00 xend = 128.0

The Volumes module in 3D slicer (v3) will load mgz files. You can use the Model Maker module to create models of your structures using the FreeSurfer label codes. http://www.slicer.org/ _ Jeffrey J. Dewey Center for Neurological Imaging Brigham and Women's Hospital

[Freesurfer] mri_compute_seg_overlap vs. mri_compute_overlap

2010-11-27 Thread Jeff Dewey
Hi all, I'm using mri_compute_seg_overlap to calculate dice coefficients for two asegs, and the numbers look reasonable. However, for two of my comparisons, mri_compute_overlap reports zero overlapping voxels between the segmentations. Do these two commands compute overlapping voxels in a dif
