Re: [Freesurfer] Can I change the pial surface outline by the adding the control point?

Hi there To my understanding, if you want to edit the pial (push it outwards more) then you need to edit the white matter, as the pial is made from the white matter surface. You can do this by manually extending the white matter surface and re-running your surfaces. Trisanna -- Ph.D. Candidate

Re: [Freesurfer] Volume to Surface

You have to run recon-all to get the surfaces of a volume. Trisanna -- Ph.D. Candidate McGill University Integrated Program in Neuroscience Psychology On Fri, Sep 30, 2016 at 9:47 AM, Crawford, Anna wrote: > Hello, > > I am trying to take nay volume that is registered and

[Freesurfer] license.txt?

Hi there I am installing Freesurfer on a Mac for the workshop next week and I cannot seem to get a license.txt because the page is no longer is accessible. However, it seems to be running fine without this file. Thoughts? Trisanna -- Ph.D. Candidate McGill University Integrated Program in

how else would you suggest I generate a colour bar? tksurfer doesn't appear to be working for me either. Best Trisanna -- Ph.D. Candidate McGill University Integrated Program in Neuroscience Psychology On Mon, Sep 12, 2016 at 7:53 PM, Trisanna Sprung-Much < trisanna.sprung-m...@mail.mcgill

[Freesurfer] colour scale

Hi there is there a way to view a colour scale bar in Freeview rather than Tksurfer, for instance, for a probability map? I can alter the Min and Max by "Configure Overlay" but cannot seem to display the bar next to my surface. Many thanks Trisanna -- Ph.D. Candidate McGill University

Re: [Freesurfer] ROIs defined in MNI space and vol2surf

Hey there I think you just need to use "--regmethod subject" instead of specifying a registration .dat file. I had similar troubles a few months ago as my labels were made on the volume and I simply wanted to overlay them onto their surfaces in Freesurfer and didn't want any transformation to be

[Freesurfer] Freesurfer 6.0?

Hi there Do we have a potential date for the Freesurfer 6.0 release? I was told I would want to re-run all my subjects to create better surfaces using Freesurfer 6.0 and I am wondering if it really will improve surface extraction that much. Many thanks! Trisanna -- Ph.D. Candidate McGill
