really? Hmmm, that sounds like a bug. It should be: labels --> indices of the most likely label at each voxel priors --> the probability that that label occurs at that voxel means --> the mean intensity of the most likely label
you can also use -nth $frame instead of #$frame On Thu, 28 Jan 2010, Guang Zeng wrote: > > Hello, Bruce, > > Thanks a lot for your quick reply? > Could I ask what is the difference between labels.mgz and priors.mgz (or > atlas.gca#1 and atlas.gca#2). > I load both of them in tkmedit, move the mouse in the image, they all gave me > the same value. > > > Thanks! > Guang > >> Date: Thu, 28 Jan 2010 16:51:56 -0500 >> From: fis...@nmr.mgh.harvard.edu >> To: freesurfer...@hotmail.com >> CC: freesurfer@nmr.mgh.harvard.edu >> Subject: RE: [Freesurfer] how to view .gca file >> >> Hi Guang, >> >> it should be: >> >> mri_convert atlas.gca#0 means.mgz >> mri_convert atlas.gca#1 labels.mgz >> mri_convert atlas.gca#2 priors.mgz >> >> cheers, >> Bruce >> >> p.s. sorry, I don't think the gca format is documented anywhere, but you >> are welcome to the code if you want >> >> On Thu, 28 Jan 2010, Guang Zeng wrote: >> >>> >>> Hello, Bruce, >>> >>> Thanks for your reply.
