[Freesurfer] automated brodmann parcellation

2011-08-16 Thread Corey Keller
Hi Freesurfers, I was wondering if you have come across a method to automatically parcellate the whole brain into Brodmann areas. I know the newest freesurfer version does this for several BAs but not all BAs have been incorporated. I was wondering if anyone knows of an existing Brodmann atlas (fo

[Freesurfer] mni or tal to brodmann's

2010-06-21 Thread Corey Keller
Hi freesurfers, I am wondering if there is a function in freesurfer to convert mni or talairach coordinates to brodmann's areas. I am hoping to input my RAS coordinates, transform them to either mni or talairach (which I know how to do), and then convert to and output the brodmann area. Thanks in

[Freesurfer] RAS to talairach transform

2010-06-23 Thread Corey Keller
Hi freesurfers, I am trying to convert electrode coordinates from RAS to talairach space. I have 128 electrodes sitting directly on the pial surface which was created from recon-all. I see that the output of each reconstruction has two transforms, talairach.xfm and talairach.auto.xfm. There seems

[Freesurfer] Plotting functional data on surface

Hi Freesurfers, I know this is probably an easy question, but I am having some trouble with it. I am trying to plot functional data (in nifti format) onto a pial or inflated surface in matlab. I am uring mri_vol2surf but am missing the register file. Do I find this from registering the functional

Hi Freesurfers, I have talairach coordinates of electrodes sitting on the brain. I am hoping to use the Desikan-Killiany parcellation scheme to determine which cortical region each electrode lies closest to in standard space. I am using read_annotation in matlab to read the lh.aparc.annot file and
