Reference volumes
by Martin Kavec 04 Mar '07

04 Mar '07

Hi, I am wondering, whether there has been any publication, or any other resource, with reference volumes of ALL the segmented subcortical structures for different age categories. I tried to search the mailinglist archives, but no success.

Runtime for -subcortseg
by Martin Kavec 04 Mar '07

04 Mar '07

Hi, anybody knows, how long does it take to run one subcortical segmentation on a MacPro? It take about 6 hours on my MacBook Pro, so I would expect it should finish faster on the workstation. Could anybody suggest me a hardware configuration, on which it could be about 4 hours? Last question, is/can be/will be the freesurfer's code parallelized? Thanks in advance, Martin -- ********************************** Senior Research Associate in Neuroradiology MRI Unit of the Department of Radiology Erasme Hospital Lennik Street 808 B-1070 Brussels BELGIUM tel: +32-2-555-4325 fax: +32-3-555-3994 email: kavec(a)messi.uku.fi ********************************** ----------------------------------------------- Find a way, or make one!

preproc inorm question
by Cameron Ellis 02 Mar '07

02 Mar '07

Hi all, If I were to perform a surface-based analysis, resampling to spherical space, and I did not want to smooth in the volume, would I need to preprocess my data again without smoothing or could I just specify the motion corrected volume in in a new analysis. I think the answer is: I could just specify the motion corrected volume, however, since the global mean for intensity normalization is calculated at the end of preprocessing after smoothing and exists in the fmcsm.meanval file, will there be a problem with the inorm in later stages, will it be performed etc. if I just specify the fmc volume in a new analysis? Thanks, Cameron

tksurfer window too small
by Joongnam Yang 02 Mar '07

02 Mar '07

Hi all, When I displayed a flattened image of the entire cortex (lh.full.patch.flat) on the tksurfer window, the image was too big for the tksurfer window, meaning the falttened image is chopped out. Is there any way that I can display the entire flattened image on the tksurfer window? Thanks. Nam.

Hello, I'm trying to run the longitudinal processing pipeline, but can't figure out a command that works. Below is what I've tried and what has happened (MC-07M_prereconEDIT is the 'pre' timepoint, and MC-07M_post is the 'post'). Can you help?

I am attempting to view the mgz files after converting from ima to mgz successfully.

can not see surfaces
by Burak Ozkalayci 01 Mar '07

01 Mar '07

Hi all, I am new to freesurfer. I just installed the freesurfer 3.0.5 to my computer (fedora core 6 x86_64). I do the steps described in the wiki for the installation and then checked whether it is working. The tkmedit works properly. However tksurfer has some problems in rendering the surface. The program works with no error : ----------------------------------------------------------------------------- "tksurfer bert lh pial" command output [root@localhost freesurfer]# tksurfer bert lh pial surfer: current subjects dir: /usr/local/freesurfer/subjects surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /usr/local/freesurfer Talairach transform /autofs/space/freesurfer/subjects/bert/mri/transforms/talairach.xfm does not exist ...

I tried the right and left hemispheres, but the same result. I also add the image of the tksurfer window to the attachments. I guess there is a opengl rendering problem. I believe my grapics card is working properly. I also add the output of glxinfo command to the end of the mail. Do you have any suggestions for my case. Thanks a lot in advance.

annotations & functional activation
by oxro03＠yahoo.com 01 Mar '07

01 Mar '07

Hi Freesurfers, I have functional activation files (.mgh) which I can overlay onto a subject's surface. Now I am trying to do a functional ROI analysis based on the annotation files, e.g. to get information about the mean activation in a specific area based on FS segmentations. Does anybody have any suggestion on how to do this in a straightforward manner? Thanks a lot. Sandy --------------------------------- Any questions? Get answers on any topic at Yahoo! Answers.

bus error during group analysis
by Leonardo Bonilha 28 Feb '07

28 Feb '07

Hi, I am getting a bus error during a group analysis and I wondered if someone could give me some help. I am running FreSurfer 3.0.5 on an intel Mac (MacBookPro 2.33Ghz, 3Gb, MacOSX 10.4.8). While going through the steps from the web tutorial (with my own data) I am getting the following message: After the command: mri_glmfit --y lh.age.thickness.10.mgh --fsgd age_fsgd.txt doss --glmdir lh.age.glmdir --surf average lh --C age.mat gdfReadHeader: reading age_fsgd.txt INFO: gd2mtx_method is doss Reading source surface /Applications/freesurfer//sub_aging//average/surf/lh.white reading group avg surface area 782 cm^2 from file Reading in average area /Applications/freesurfer//sub_aging//average/surf/lh.white.avg.area.mgh Number of vertices 163842 Number of faces 327680 Total area 67091.234375 AvgVtxArea 0.409487 AvgVtxDist 0.738119 StdVtxDist 0.221868 $Id: mri_glmfit.c,v 1.78.2.7 2007/01/23 21:37:47 greve Exp $ cwd /Applications/freesurfer/sub_aging/stats cmdline mri_glmfit --y lh.age.thickness.10.mgh --fsgd age_fsgd.txt doss --glmdir lh.age.glmdir --surf average lh --C age.mat sysname Darwin hostname Macintosh.local machine i386 user leonardobonilha FixVertexAreaFlag = 1 OneSampleGroupMean 0 y /Applications/freesurfer/sub_aging/stats/lh.age.thickness.10.mgh FSGD age_fsgd.txt glmdir lh.age.glmdir Creating output directory lh.age.glmdir Bus error Interestingly, I ran the same analysis (with the same data) on another machine (this time a PC running Ubuntu) and it went fine, without any problems. Thanks for the support Leo Leonardo Bonilha MD PhD Research Assistant Professor Dep of Neuropsychiatry and Communication Sciences and Disorders University of South Carolina ____________________________________________________________________________________ TV dinner still cooling?
