tksurfer & mris_anatomical_stats
by Moran Artzi 10 Feb '12

10 Feb '12

Dear experts, I'm a new user in freesurfer and mainly interest in the motor area cortical thickness. I have several question: * Using tksurfer SubFolder lh inflated Curvature---> lh.curv / lh.thickness / lh.volume ... *1. How can I detect the motor area location (i.e. translate the give coordination's)? 2. What are the units of the *.curv *curvature pattern map? 3. All curvature maps are given in Red/Green colors, can it be changed? 4. How can I insert color bar? Using *view>color scale bar* insert fixed bar only (ranged -5-5; not Red/Greed colored) I would like to have the full statistic report for given hemisphere;Using the command : *mris_anatomical_stats -a SubFolder /label/lh.aparc.annot -b lh >>out.txt *seems to provide only partial information, are there other parameters that should be added? Thank you in advance for your help Moran

Segfault using optseq2 and tnullmin
by jl123＠gmx.de 10 Feb '12

10 Feb '12

Hi everyone, I'm using optseq2 to optimize a fmri design. Whenever I try to add the --tnullmin parameter I end up with either a segmentation fault or a glibc error (see examples). May someone explain me what is going wrong? Thanks! Regards, Jacob Info: optseq2 2.14 linux 64-bit and 32-bit Example that works: optseq2 --ntp 300 --tr 3 --psdwin 0 30 1.5 --ev precision 6 50 --ev power 6 50 --nkeep 1 --o ex2 --nsearch 1000 --cost eff Example with segfault: optseq2 --ntp 300 --tr 3 --psdwin 0 30 1.5 --tnullmin 6 --ev precision 6 50 --ev power 6 50 --nkeep 1 --o ex2 --nsearch 1000 --cost eff Example with glibc error: optseq2 --ntp 300 --tr 3 --psdwin 0 30 1.5 --tnullmin 3 --ev precision 6 50 --ev power 6 50 --nkeep 1 --o ex2 --nsearch 1000 --cost eff -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

Hello, I am using a DELL precision T3500 on Mandriva 2008 my SUBJECTS_DIR is : /neurospin/grip/protocols/MRI/childrenNS5_7y_Monzalvo_2012/Subject/ (from the "neurospin/grip" network in my lab).

Segmentation
by Alana Shepherd 09 Feb '12

09 Feb '12

Hi Freesurfers, I've been using version 5.1 and looking at the desikan parcellation. I've been finding in quite a number of participants that the insula is extending medially towards the accumbens region (example screen shot attached), and wondered whether this is something I need to be manually editing. What would you advise? Kind regards, Alana Shepherd

How do I compile a table from several hundred "wmparc.stats" files?
by Tracy Abildskov 09 Feb '12

09 Feb '12

Hello surfers: I was wondering if there is a command like "aparcstats2table" or "asegstats2table" that would work with data in the "wmparc.stats" files. If I needed to compile the data on just a few scans I would not post this question. The problem is I need to compile this list on several hundred analyzed scans. Thank you, in advance, for any help you can offer. BA P.S. I know that wmparc.stats is not as good as aseg.ststs however it is the only place I can find some of this types of data.

wm_excluded
by Gabor Perlaki 09 Feb '12

09 Feb '12

Dear all, I'm new in freesurfer. I ran "recon-all -all" on 8 subjects without error, and I loaded the wm.mgz and the surfs. White matter surface (yellow line) seems pretty good by visual inspection, but the wm.mgz seems not so good everywhere. There are certain white-matter areas, which are clearly inside the yellow line (WM surface) but they are not considered as white-matter on the wm.mgz image. So it seems for me that calculating white-matter volume is more accurate using the white-matter surface instead of wm.mgz. What does wm.mgz used for? Does it has any impact on the white-matter volume reported by freesurfer? Is it a problem, that wm.mgz doesn't fit well the white-matter surface everywhere? What is the reason that wm.mgz doesn't fit the WM surface everywhere? Thanks a lot, Gabor

I'm following the tutorial at http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis . I'm pretty sure I have my directories set up properly and I've used Mricron's dcm2nii tool on my raw functionals/structurals. I've also already successfully preprocessed my data and made the rtopy.par files (preproc-sess & mkanalysis-sess). I haven't been able to find a response that fixed the problem and was hoping for some suggestions. Thanks so much, Daniel -- Daniel Cole University of Rochester Brain and Cognitive Sciences dcole10(a)u.rochester.edu

Pial and white surface defects.
by Rashmi Singh 09 Feb '12

Hello, I had this issue raised earlier, but may be it got lost in the pile of questions you receive everyday. I am very new to freeSurfer, and may be its me who is dong something wrong so please advise. I am getting defects in the volume output of freesurfer with respect to the pial surface and whilte-matter surface boundary. I am wanting to measure the cortical thickness after running recon_all. I was inspecting the pial and white surface using tkmedit and I noticed (volume data view using tkmedit) that in most of my subjects the freesurfer has included non-cortical matter (ex: cerebellar regions) as cortical matter and have excluded several white matter voxels. I use brainmask volume loaded as main volume and white matter volume loaded as aux volume to inspect the final pial and white surfaces. These defects are more clearly visible when I get the subcortical segmentation in on mode to be viewed or when I am viewing the pial/white surface boundaries in the images where brainmask is loaded as main volume with T1.mgz as the aux volume and subcortical segmantation in on mode. Interestingly such defects were found in same regions across the subject and are present in more than one section. If what I am seeing are defects, this would be require too much editing. Please advise Rashmi. ________________________________ This document may contain information covered under the Privacy Act, 5 USC 552(a), and/or the Health Insurance Portability and Accountability Act (PL 104-191) and its various implementing regulations and must be protected in accordance with those provisions.

I have CentOS 5 installed through VMware player on a WIn 7 desktop . I had freesurfer installed on it and I was running a subject . This subject ran through completely on freesurfer installed on MacOSx. However on the virtual Linux setup it failed with the following error Loading Source Label Invalid Argument Error reading from <Data Folder>/fsaverage/label/lh.BA1.label. I checked and did not find this folder in the system. I was hoping if someone here has any idea of what went wrong Regards Darshan
