[Freesurfer] Keeping edits

2005-10-18 Thread Fornito, Alexander
Hi, Is there any way to run autorecon2-cp with an edited brain volume so that it concurrently adjusts the pial surface. Everytime I try to run it, it seems to erase my edits to the brain volume. Howeever, running autorecon2-wm or -pial, uses the brain edits. Some help on this would be much appre

Hi Alex, I've looked into your problem and I do see what you mean. Here's a brief run-down on the different flags. -autorecon2-cp begins with -normalization2, using your control points. Problem is it WILL write over the brain volume, creating a new one. It then finishes the stream from her

If you don't have a surface, then don't run it with --surf. It's important to have an accurate talairach.xfm. doug On Mon, 17 Oct 2005, Sasha Wolosin wrote: Dear Nick, I recently installed the dev release from October 3rd, but tkregister2 still does not work after autorecon1. (It will

My subject's anatomical scan seems to be relatively well aligned with the fuzzy talairach brain, but the green 'orig' surface is completely off. How is this possible? Why do we need the surface at all if it's not used for alignment? The tutorial advises using the 'final objective function

Sasha, We are updating our tutorial to make it clearer how and when to correct a bad talairach alignment. The tutorial assumed that recon-all - autorecon-all was run, which would have created surfaces (which might not have been fully correct, but good enough to check talairach alignment). In you
