[Freesurfer] Warping to MNI space

2013-11-17 Thread ebelleau
Hello, I plan on using the aseg.nii to create a grey matter mask. I want to warp these grey matter masks to MNI space. I have been trying to use @auto_tlrc in AFNI to do this warping but am having some trouble. The reason I need this in MNI space is because I plan to make a group grey matter

Ok perfect. Just one last question, how would I use the thresholded option for the annotations (i.e. aparc.DKTatlas40.annot, aparc2009s.annot) when doing whole brain analyses? Thanks! On Sun, Nov 17, 2013 at 1:20 PM, Bruce Fischl wrote: > for most purposes, yes > > Bruce > On Sun, 17 Nov 2013,

Great thanks Bruce! I'm assuming then that using the thresh.label is the best choice. On Sun, Nov 17, 2013 at 12:50 PM, Bruce Fischl wrote: > Hi Krista > > the unthresholded labels give every point that has a non-zero probability > of being in the label, no matter how unlikely. The .thresh ones

Hi Krista the unthresholded labels give every point that has a non-zero probability of being in the label, no matter how unlikely. The .thresh ones are thresholded to pick the most likely vertices that give a label that is the right surface area. cheers Bruce On Sun, 17 Nov 2013, krista kelly

[Freesurfer] .label versus .thresh.label

2013-11-17 Thread krista kelly
Hi, I've just started using the newest freesurfer v 5.3 and I've noticed in the labels folder that every .label has a thresh.label. When overlaying the two, they can be quite different (for example MT.label is much larger than MT.thresh.label) or quite similar (V1.label is just a tiny bit larger th
