If I am to introduce further areas for projection (or construction on the surface), what procedure should I follow? Thanks, Eylem Nick Schmansky wrote: The BA/MT/V1/V2 maps are label files in the subjects/fsaverage/label directory distributed with freesurfer. See also: http://surfer.nmr.mgh

Hi Eylem, I'm not sure what you mean. Do you mean you have some new areas that you want to project onto the surface of an existing subject? For that you will need the subject surfaces, which we are happy to give you. cheers, Bruce On Wed, 27 May 2009, Eylem Kirlangic wrote: If I am to intr

The units of the max are the same as the units of the input. The Tal xyz are MNI305 converted to talairach with Matthew Brett's transform. The conversion can be turned off with --nofixmni. Some of this stuff is discussed in the --help. doug Siddharth Srivastava wrote: Hi everyone,

[Freesurfer] source code for FreeSurfer and comparison with Neuroquant

2009-05-27 Thread John Drozd
Hello, I am reviewing the papers outlined in the "FreeSurfer Analysis Pipeline Overview". I would find it helpful if I could download the source code for FreeSurfer. Please let me know if this is at all possible. Also I was wondering how different Cortech's commercial sister program to FreeSurfer

[Freesurfer] mri_glmfit and dofs

2009-05-27 Thread Georg Homola
Hi Doug! When performing surface-based group analysis with mri_glmfit, I have to specify the dofs of my feat runs. But when I correct for motion outliers on first level (by additional confound EVs identified by fsl_motion_outliers) there will be different dofs for every subject. Is a correct group

2009-05-27 Thread Douglas N Greve
You only need to spec the dofs with a fixed effects analysis. If that's what you are doing, then you need to sum all the dofs from the lower level. doug ps. these types of questions are better to post to the freesurfer mailing list Georg Homola wrote: Hi Doug! When performing surface-based

[Freesurfer] Problem viewing sig overlay?

2009-05-27 Thread Nasim Maleki
Dear FreeSurfers, I'm trying to transform and overlay the sig.mgh files on the 3D volumetric data. I use mri_surf2vol to convert sig.mgh and everything works fine up to the point that I try to view the overlay with tkmedit. There is no overlay on top of the main volume although it is suc
