Hi, I have finished 3 demension data management by the Freesurfer software, but I do’t know how to compare the cortical thickness of the occipital lobe between the patient group and the control group. Could you tell me the way to deal with that? Thank you very much! hankee，duhanjian(a)sohu.com 2007-5-25

Gammafit vs. SPMHRF
by Dan Dillon 21 May '07

21 May '07

Dear FreeSurfers, What exactly is the difference between the HRF function in gammafit vs. SPMHRF? Are there reasons to prefer one to the other? Thanks, Dan Dillon, Ph.D. Post-doctoral Fellow Affective Neuroscience Lab Dept. of Psychology, Harvard University Phone: (617) 496-5222 E-mail: dillon(a)wjh.harvard.edu

Hi, I'm still having problems with make_average_subject, when I type the folowing command line in: >make_average_subject --debug --subjects 'subject1' 'subject2'..... --out PLP_average --no-symlink echo ERROR: Flag $flag unrecognized. echo ERROR: Flag --no-symlink unrecognized. ERROR: Flag --no-symlink unrecognized. echo $cmdline echo ....... exit 1 exit 1 and when I try to view the results by > tksurfer PLP_average lh inflated I get the message: surfer: current subjects dir: /disc2/Kate/Flatmap1 surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /disc2/Kate/Flatmap1 surfer: ### Could not find anatomical header information. The mri folder does not contain the same files that the tutorial example subject 'buckner fsaverage' does, what do you think is going wrong? Thanks for your help Best wishes Carolyn

RE: [Freesurfer] tkmedit
by Jenni Pacheco 21 May '07

Hi Martin, You should be fine not editing these regions routinely - only, of course, if they pose a problem for your surfaces. For the most part, also, you should be fine to run the entire stream and do any edits that may be needed after the fact - instead of running stepwise and checking each output along the way.

Changing the color in Edit Segmentation tool
by Jared Conley 18 May '07

18 May '07

I am attempting to edit the segmentation results in TkMedit, according to the following Wiki directions ( > TkMeditGuide/TkMeditWorkingWithData/TkMeditSegmentations): A segmentation can be edited with the Edit Segmentation tool, which can be activated by pushing the icon_copy.gif button on the Main Toolbar, by choosing *Tools->Edit Segmentation*, or by pressing the 'g' key. By clicking with button 2 with this tool, you can 'paint' a label in the segmentation. The color used can be set in the dialog box brought up by choosing *Tools->Configure Segmentation Brush....* However, I am not able to change the color to match the structure I am wanting to edit (I have tried selecting three different structures at random and the color of the editing remains grey). Any ideas?

Hi Annie, The aparc+aseg has the aseg subcortical labels in the wm regions, and has the parcellation labels along the cortex. This is overlaid on volumes in tkmedit. A description and a snapshot is shown at the bottom of this page: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/OutputData Jenni On Fri, 18 May 2007, Annie Chiu wrote: > Hi Jenni, > > Thanks very much for your speedy reply.

probabilistic labels
by Wanmei Ou 18 May '07

18 May '07

Hi, Is there a way to get probabilistic labels for ?h.sphere.reg? If I understand it right, mris_ca_label oand mris_divide_parcellation only return the MAP solution of the probabilistic labels. Thanks, Wanmei
