How does freesurfer take the individual landmarks of different regions take into acccount
by Klein, Holger 11 Jun '13

11 Jun '13

Dear Bruce et al., Submitting a paper in which I use freesurfer for the analysis of the auditory cortex, I was asked how freesurfer actually takes individual boundaries (e.g. of Heschl's gyrus) into account? Both atlases (Desikan and Destrieux) are based on about 10-20 subjects. How are these boundaries transferred to other subjects? As far as I understood the description of freesurfer there aren't any templates (or some kind of masks) which are put on the subjects to analyse. What's the "secret" or principle behind the individual analysis to receive reliable data for every ROI of every subject (in a nutshell)? Thanks in advance, best wishes, Holger

How to measure the surface dimension in a mask image after mri_glmfit?
by Glen Lee 11 Jun '13

11 Jun '13

Dear freesurfer users I'm wondering if there is any way of figuring out the surface size within a mask image (mask.mgh) which is generated after running a group-level GLM analysis (2nd RFX) using mri_glmfit. As I'm thinking, this may be: number of vertex by dimension of one vertex (1mm). But I could be wrong and let me know if anyone knows the solution. -Glen fyi) the group analysis was performed in freesurfer sym space.

Dear All, If I had to choose between longitudinal processing v4.4 or cross-sectional processing v5.1 for analyzing longitudinal data, what processing stream should I choose?

Re: [Freesurfer] environment variable FREESURFER_HOME
by zkaufman＠nmr.mgh.harvard.edu 11 Jun '13

11 Jun '13

Pablo, The .cshrc and .bashrc files we are referring to are not Freesurfer files and do not come with the Freesurfer distribution. They are files that can (although not always) exist in the home directory of your computer. Do not modify the the .csh or .sh files that come with Freesurfer. That is for the expert user. If you want to use Freesurfer just open a command line and type the following: (if using csh) setenv FREESURFER_HOME Applications/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.csh (if using bash) export FREESURFER_HOME=/Applications/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.sh If you dont want to type these commands everytime you want to start using freesurfer than you can add these lines to your .csh and .bashrc *in your home directory*. If those files do not exist than you may create them *in your home directory* and simply add those two lines to the file. -Zeke > Dear Freesurfer experts, > I am trying to install free surfer. > It seems that my downloaded version does not have a .cshrc file.

Fwd: Talairach Positioning in Horizontal View
by Peter Boulos 11 Jun '13

11 Jun '13

I am very new to the software and have just begun assessing Talairach outputs for my subjects. I am confused in that I cannot seem to find a balance I am happy with between positioning of the green lines in both the horizontal and sagittal views for multiple subjects. I opened the talairach output with the following command (tkregister2 --mgz --s SUBJID --fstal --surf orig) and everything looked perfectly aligned for all the subjects I have tried in both the coronal and sagittal views but in the horizontal view the green lines went well off the back of the brain. I have attached a screenshot. I tried to translate the brain but that did not seem to solve my issue and I realized I needed to scale the length of the brain. When I did that I was more pleased with the outcome but the corpus callosum did not match up nearly as well after I did that (second attached screenshot) and that was the primary landmark I was using to pass my images in terms of talairach output assessment. Do you have any advice for me? Peter
